An LP (Listening Post) is a position established to detect threat movement by sound — typically forward of the perimeter in low-visibility conditions. An OP (Observation Post) provides visual coverage of a designated sector. Most positions serve both roles. Each post gets a designation, sector coverage, manning requirement, and communication protocol. Pulls personnel data from ROSTER.
A sound perimeter uses layered defense — early warning layer, outer delay layer, and inner defensive positions. Define your perimeter sectors here, assign personnel responsibilities from your Roster, and document the logic behind your position layout. No classified information — describe using compass bearings and distance from reference points only.
Dead ground is terrain that cannot be observed or engaged from a position — every defensive layout has it. Identifying dead ground before it matters means you can cover it with an alternate position, wire obstacle, or early warning device. Interlocking fields of fire ensure that the dead ground of one position is covered by an adjacent position. Document both here.
Challenge and response prevents fratricide — shooting your own people in low-visibility or high-stress conditions. Every member of your group must know the current challenge/response pair. Rotate pairs regularly — weekly minimum in an active scenario. Include a duress word — a specific response that tells the post the person is being coerced. The post acknowledges normally but initiates the threat response protocol.
Rules of engagement define when force is authorized, what level of force is appropriate, and who has authority to escalate. In a grid-down scenario, these decisions need to be made in advance — not in the moment under stress. A clear ROE framework also protects your group by ensuring everyone is operating from the same standard. This document is for internal use only.
A sector sketch (range card) documents what a specific position can engage, what it cannot, key range references, and the position's relationship to adjacent positions. Each position that will be occupied during an alert or watch should have a sector sketch. These are printed, laminated, and left at the position — not carried by the person manning it.
Two kinds of output live here. The Complete Security Plan prints everything you have entered as one ordered document for a 3-ring binder. The four field cards below print small, laminate-ready references that go in a pocket or stay at a position. Print outputs open in a new tab and send straight to your printer or "Save as PDF."
One continuous document containing every section you have filled in: perimeter design, the full LP/OP registry, fields of fire and dead ground, challenge & response protocols, rules of engagement, and all sector sketches. Cover page, table of contents, page breaks between sections. This is the version you three-hole-punch and put in the binder.
Current C/R pairs, duress word, rotation, and visual recognition signals. Wallet-sized, laminate and carry. One per member.
All LP/OP positions with type, sector coverage, manning, comms, and reporting protocol. One page; post it at the operations center.
One full-page range card per defined sector. Left and right limits, range references, dead ground, adjacent positions. Stays at the position.
Condensed escalation ladder and authority matrix. For all personnel, not just post commanders. Laminate and carry.
This manual assumes you have never opened BREACH POINT before and explains everything from zero. Every screen is described and the important ones are drawn out. Work through it in order the first time. After that, use the table of contents to jump to what you need.
BREACH POINT is the tool for working out, in advance and in calm conditions, how your location is watched and defended. A breach point is any place an intruder could get in. The program walks you through finding those places and deciding what you will do about them before anything happens.
It does six jobs for you:
Good security is not one wall. It is layers, each one buying you time and warning. The outer layer warns you something is coming. The middle layer slows it down. The inner layer is where you make a stand. BREACH POINT is organized around these layers.
| Warning layer | Your LPs and OPs sit here (Module 01). Their only job is to detect and report — not to fight a battle alone. |
| Delay layer | Natural and built obstacles that slow an approach and channel it where you want it. Documented in Perimeter Design (Module 02). |
| Defensive layer | The positions you actually fight from, each with a sector sketch (Modules 03 and 06). |
The window has four parts. They never move, so once you learn them you always know where you are.
Do not try to fill in everything at once. Follow this order; it matches how the layers stack up.
This is the master list of every watching position. Click + ADD LP/OP POSITION to create a card and fill it in. Add as many as you have.
| Designation | A short name you will say on the radio: OP-1, LP-North, etc. |
| Type | LP (listens, usually night), OP (watches a sector), or LP/OP (both). Most are both. |
| Sector covered | The slice of ground this post is responsible for. Use compass bearings or landmarks: "NE, the wood line to the gate." |
| Manning | How many people and for how long. A post you cannot keep manned is a plan, not a reality. |
| Comms | How the post reports in — radio channel, call-in schedule, signal if radios are down. |
| Location reference | Where it is, described from a known point. No coordinates needed: "behind the stone wall, 40m up the east fence line." |
One screen of plain-text boxes that capture the big picture of your defense. Fill in what you can; leave the rest for later.
A field of fire is simply the ground a position can cover. This screen records, for each position, where its coverage starts and stops, and — just as important — the dead ground it cannot reach.
Click + ADD POSITION FOF ENTRY for each position. For each one, note the left and right limits, the farthest useful range, the key reference points you would call out, and any dead ground.
Interlocking fields of fire means the dead ground of one position is covered by the next position over. When you can say that about your whole perimeter, you have no blind seams.
This is the password system that keeps you from firing on your own people in the dark or under stress. Everyone in the group must know the current pair.
| Challenge | The word the post calls out. Example: IRON. |
| Response | The correct answer. Example: RIDGE. Wrong answer = treat as unknown. |
| Duress word | A response that means "I am being forced." The post answers normally but quietly starts the threat plan. |
| Rotation | How often you change the pair. Weekly minimum during an active situation. |
| Visual signals | Day and night recognition signals for when calling out is unsafe. |
Rules of engagement decide when force is allowed, how much, and who may order it — settled in advance so nobody improvises under stress. The screen is built around a three-level escalation ladder.
| Level 1 | Unknown or uncleared approach. Challenge, halt, observe. No weapons shown. |
| Level 2 | Non-compliant or hostile intent shown. Warnings, weapons readied, all positions alerted. |
| Level 3 | Active armed attack. Authorized defensive force, defense plan initiated. |
You also record who may authorize lethal force, the self-defense exception, and special guidance for children and non-combatants and for an allied group's approach.
A sector sketch (range card) is a one-page reference for a single position. It is printed, laminated, and left at the position so whoever is on watch knows exactly what they are looking at — even on their first shift there.
Click + ADD SECTOR SKETCH per position and record the left/right limits, the primary sector of responsibility, range references (near, middle, far landmarks with rough distances), known dead ground, and the adjacent positions on each side.
The Generate Docs screen turns your entries into paper. Printouts open in a new browser tab and go straight to your printer's dialog, where you can also choose "Save as PDF."
Complete Security Plan prints everything you have entered as one ordered document — cover page, contents, then perimeter, posts, fields of fire, challenge & response, rules of engagement, and sector sketches, each starting on its own page. This is the copy you three-hole-punch for the binder.
Everything you type is stored only on this device, inside this file, under the key ao_breach_point_v1. Nothing is sent anywhere. That is the point of an offline tool — but it means the backup is on you.
| LP | Listening Post. A position placed to hear an approach, usually forward and at night. |
| OP | Observation Post. A position placed to watch a sector of ground. |
| Sector | A defined slice of ground a position is responsible for. |
| Field of fire | The ground a position can actually cover. |
| Dead ground | Terrain a position cannot see or reach, hidden by a dip, building, or vegetation. |
| Interlocking | Arranging positions so each one's dead ground is covered by the next. |
| Range card | A sector sketch — a one-page reference left at a position. |
| Challenge / response | A spoken password pair used to recognize friend from unknown. |
| Duress word | A response signaling the speaker is being coerced. |
| ROE | Rules of Engagement. Pre-decided rules for when and how force is used. |
| MAG | Mutual Assistance Group. An allied group you cooperate with. |
No. Start with Perimeter, Challenge & Response, and ROE. Add posts, fields of fire, and sector sketches as you are able to walk the ground.
On this device only, inside this file. Nothing is uploaded. Keep the file and its printouts private, and back up with the Export button.
The Post Sheet is one page listing all your posts, for the operations center. A Sector Sketch is one page per position, left at that position for whoever is on watch.
Yes. Use Complete Security Plan on the Outputs screen. It prints every section in order for a 3-ring binder.
No. The Rules of Engagement module helps you write your group's internal planning. The law where you live governs the actual use of force. Have a level-headed person review what you write.
BREACH POINT ships with a demo sandbox — a separate copy pre-loaded with a complete worked defensive plan for a ridge property: three observation posts (an LP/OP on the vehicle approach, an OP on the ridge spur, a listening post at the creek ford), two fields-of-fire positions with left and right limits and interlocking sectors, sector sketches with near/mid/far range references, a perimeter clock layout with terrain and threat analysis, a challenge-and-response card with duress word and visual day and night signals, a Rules of Engagement worksheet (use-of-force ladder, noncombatant guidance, and legal caveats), and a dead-ground worksheet with mitigation. All six modules are populated, so it reads as one coherent defense where the pieces reference each other.
Opening and leaving. In the live module, click DEMO in the sidebar under this manual. Inside the demo, that same slot reads RETURN TO LIVE and takes you back. An amber banner across the top of the demo tells you which copy you are in at all times.
Your real data is safe. The demo keeps its plan in a completely separate storage slot. Nothing you do in the demo can touch your real BREACH POINT plan.
Resetting. The RESET DEMO button (top bar and amber banner) discards any changes and restores the sample plan.
BREACH POINT helps you plan and document the security side of your location before anything happens. It is a planning tool, not legal advice and not a substitute for training. Rules of engagement written here are for your group's internal planning only. Keep this file and its printouts private.
A breach point is any place an intruder could enter. The program walks you through finding those places and deciding what to do about them in advance. It registers your listening and observation posts, designs your perimeter, maps fields of fire and dead ground, sets your challenge-and-response password system, records your rules of engagement, and prints field cards plus a full binder document so everyone works from the same plan.
Security is layers, not one wall. The early-warning layer (LPs and OPs) tells you something is coming. The delay layer (obstacles and terrain) slows it and channels it. The defensive layer is where you make a stand. Every module supports one of these layers: detect, delay, then — only if your rules of engagement allow — respond.
Four fixed parts. The top bar shows the suite name, a return to Command Suite, and the settings gear. The left sidebar lists the six modules, then Outputs, then Help. The main work area is where you type. The bottom action bar holds CLEAR and the green SAVE. The tool also auto-saves as you type.
Work in this order: (1) Perimeter Design — describe your place; (2) LP/OP Registry — add one or two watch positions; (3) Challenge & Response — set a challenge, response, and duress word; (4) Rules of Engagement — write the three threat levels in your own words; (5) Outputs — print the Complete Security Plan for the binder. A rough plan written down beats a perfect plan in your head.
The master list of watching positions. Each card holds a designation (OP-1, LP-North), a type (LP, OP, or both), the sector covered, the manning required, the comms plan, and a location reference described from a landmark. Describe positions by bearing and distance from landmarks, never by anything that would let a stranger find your home.
Plain-text boxes for the big picture: your primary defensive position, the rough radius of your rings, how the ground divides into sectors, the key terrain that helps or hurts you, and the threat approaches that need the most coverage. The approaches you list here should match where you placed your posts in Module 01.
A field of fire is the ground a position can cover. For each position, record where coverage starts and stops, the farthest useful range, key reference points, and dead ground. Dead ground — what a position cannot see — is the point of this screen: find it now and cover it with an adjacent position, an obstacle, or an alarm. Interlocking fields of fire means each position's dead ground is covered by the next.
The password system that prevents firing on your own people. Everyone must know the current challenge word and response word. A duress word, given as the response, means the speaker is being forced: the post answers normally but quietly begins the threat plan. Rotate the pair weekly at minimum, and print a fresh card each time you change it. Visual day and night signals cover times when calling out is unsafe.
Decide in advance when force is allowed, how much, and who may order it. The three-level ladder runs from an unknown approach (challenge and observe), to hostile intent shown (warnings and alert), to active armed attack (authorized defensive force). Record who may authorize lethal force, the self-defense exception, and special guidance for non-combatants and allied groups. This is internal planning only; the law where you live governs the actual use of force. Have a clear-headed person review it.
A sector sketch (range card) is a one-page reference for a single position, printed and left at that position. It records the left and right limits, the primary sector, range references near to far, dead ground, and the adjacent positions. Unlike the C/R card, it does not travel with a person; it stays at the post so every watch reads the same picture.
Generate Docs turns entries into paper; printouts open in a new tab and go to your printer dialog, where you can also Save as PDF. The Complete Security Plan prints everything in order for the binder. The four field cards are the Challenge/Response Card (pocket, one per member), the Post Reference Sheet (all posts on one page for the ops center), the Sector Sketch Cards (one page per sector, left at the position), and the ROE Summary Card (escalation ladder for everyone). If nothing prints, allow pop-ups for this file.
Everything is stored only on this device, inside this file, under the key ao_breach_point_v1. Nothing is sent anywhere. Auto-save runs as you type and the green SAVE saves immediately. Use Export All Data (JSON) on the Outputs screen to back up before clearing or moving machines, and Import to restore. Settings switches dark and light display across the whole suite. Back up after any real work and keep a copy off the machine.

Do I have to fill in all six modules? No — start with Perimeter, Challenge & Response, and ROE; add the rest as you can walk the ground. Is my data private? Yes; it stays on this device. Back it up with Export. Post Sheet vs Sector Sketch? The Post Sheet lists all posts on one page for the ops center; a Sector Sketch is one page per position, left at that position. Print everything at once? Use Complete Security Plan. Legal advice? None here; the law where you live governs use of force.
