Defense Fundamentals

Layered Security (Onion Model)

Defense works in layers. Each layer buys time and creates obstacles. No single layer is sufficient.

1. Outer perimeter: Property boundaries, fencing, gates, approach visibility
2. Inner perimeter: Building exterior, doors, windows, lighting
3. Interior zones: Room-by-room security, safe room, valuables protection
4. Personal defense: Last resort when other layers fail

Each layer should force an attacker to spend time, make noise, or take risks. The more obstacles, the more likely they give up or get caught.

Deter, Detect, Delay, Defend

Know Your Threats

Effective defense requires understanding what you're defending against:

• Opportunistic crime: Burglary, theft, vandalism. Most common. Targeting easy opportunities.
• Targeted crime: Stalking, domestic violence, personal disputes. Requires specific planning.
• Civil unrest: Riots, looting during crises. Duration hours to days.
• Home invasion: Forced entry while occupied. Highest danger.
• Extended crisis: Breakdown of law enforcement. Weeks to months. Requires community defense.

Assessment Questions

• What are the most likely threats in my area?
• What are the entry points to my property and home?
• How long until police response in my area?
• What valuables or people am I protecting?
• What are my escape routes if defense fails?
• Who are my allies (neighbors, family, community)?

Site Survey

Walk your property as an attacker would. Look for weaknesses:

• Approach routes: How can someone reach your home unseen?
• Cover and concealment: Where could someone hide or approach undetected?
• Entry points: Every door, window, access panel. Count them all.
• Lighting: Dark areas at night. Motion light coverage.
• Visibility: What can neighbors see? What can passersby see?
• Egress: How do you escape if needed? Multiple routes?

Do this at day and night. Threats operate in both conditions.

Common Vulnerabilities

Escalation Ladder

Know what you'll do at each stage. Panic is the enemy.

1. Detection: Alert received (alarm, noise, dog barking). Assess situation.
2. Verification: Confirm threat. Check cameras, look outside, listen.
3. Alert: Call 911. Alert family members. Don't assume others heard.
4. Secure: Lock doors, gather family, move to safe room if appropriate.
5. Defend: If threat enters, defend yourself. Know your legal rights.
6. Aftermath: Secure scene, document, contact insurance, address trauma.

Communication Plan

• Code words: Family knows "get inside now" vs "lockdown" vs "leave immediately"
• Meeting points: Where does family go if separated? Near home, neighborhood, out of area?
• Emergency contacts: Who do you call? Police, neighbors, family?
• Out-of-area contact: Someone outside your region to coordinate if local lines down

Know Your Local Laws

• Castle doctrine: Some states allow force against intruders in your home without duty to retreat
• Stand your ground: Some states extend castle doctrine outside the home
• Duty to retreat: Some states require retreat if possible before using force
• Proportional force: Force used must be proportional to threat in most jurisdictions
• Citizens arrest: Limited authority, significant legal risk if done wrong

This is general information, not legal advice. Laws vary by state and locality. Know your specific laws before a crisis.

Break-in During Day

1. Get to safety (lock in room, exit if possible)
2. Call 911 immediately
3. Do not investigate sounds
4. If confronted, comply if no escape route
5. Memorize attacker description

Home Invasion at Night

1. Gather family to safe room
2. Lock door, call 911
3. Arm yourself if trained and legal
4. Announce you're armed and police are coming
5. Do not leave safe room until police arrive

Civil Unrest Nearby

1. Monitor situation (news, social media, scanner)
2. Secure property early (before threat arrives)
3. Stay inside, avoid windows
4. Have go-bag ready if evacuation needed
5. Coordinate with neighbors if safe
