# Defensive Architecture

## 매 한 줄
> **"매 base 의 geometric layering"**. 매 attacker 의 multi-kill-zone 의 force. 매 cross-fire field. 매 modern: 매 platform-specific resistance + 매 EW (electronic warfare) bunker. 매 [[Combined Arms (제병협동) 전술]] + [[Baiting]] 의 응용.

## 매 핵심 principle

### Function > Form
- 매 high-value 의 center.
- 매 expendable 의 outer.

### Layered Defense
- 매 multiple ring.
- 매 매 ring 의 specific role.
- 매 attacker 의 매 ring 의 통과 의 force.

### Kill Zone
- 매 cross-fire of N turrets.
- 매 attacker 의 most damage.

### Funnel
- 매 wall 의 narrow path.
- 매 mine field + concentrated fire.

### Heterogeneous defense
- 매 다양한 turret type.
- 매 매 damage type 의 cover.

### 매 modern (Arc 2 / WARNO style)
- 매 platform 의 50% damage type resistance ([[Arc 2 기술 및 2026년 연구 업데이트(March 2026 Research Drop)]]).
- 매 EW field (Nightwatch turbulence).
- 매 mixed garrison.

### 매 typical layout

#### Square Base
- 매 corner 의 turret.
- 매 wall 의 perimeter.
- 매 가장 generic.

#### Blitz Base
- 매 long-range turret 의 spread out.
- 매 baiting 의 counter.

#### Honey Pot
- 매 fake weak spot.
- 매 mine concentration.
- 매 ambush.

#### Ring base
- 매 concentric defense.
- 매 가장 expensive 가 매 strong.

### 매 anti-baiting layout
- 매 long-range hidden 의 spread.
- 매 funnel attacker 의 mine.

## 💻 패턴 (응용 — RTS / tower defense design)

### Base layout validator
```ts
interface Building { id: string; type: string; pos: Vec2; range: number; }

function validateLayout(buildings: Building[]): ValidationResult {
  const issues: string[] = [];
  
  // 매 1. core building 의 center 의 protect
  const cores = buildings.filter(b => b.type === 'command_center');
  for (const core of cores) {
    const enclosingRing = buildings.filter(b => 
      b.pos.distance(core.pos) < 30 && b.type !== 'command_center'
    );
    if (enclosingRing.length < 5) issues.push('Insufficient outer ring');
  }
  
  // 매 2. cross-fire coverage
  const turrets = buildings.filter(b => b.type === 'turret');
  for (const turret of turrets) {
    const overlap = turrets.filter(t => 
      t.id !== turret.id && t.pos.distance(turret.pos) < t.range + turret.range
    );
    if (overlap.length < 2) issues.push(`Turret ${turret.id} no cross-fire support`);
  }
  
  return issues;
}
```

### Kill zone calculator
```ts
function killZoneIntensity(point: Vec2, turrets: Building[]): number {
  return turrets.filter(t => point.distance(t.pos) < t.range).length;
}

function generateKillZoneHeatmap(map: Map, turrets: Building[]): number[][] {
  const heatmap: number[][] = [];
  for (let y = 0; y < map.height; y++) {
    heatmap.push([]);
    for (let x = 0; x < map.width; x++) {
      heatmap[y].push(killZoneIntensity(new Vec2(x, y), turrets));
    }
  }
  return heatmap;  // 매 visualize: 매 zones with 3+ overlapping turrets.
}
```

### Funnel design
```ts
function computeFunnel(walls: Wall[], entry: Vec2): Path {
  // 매 path-finding 의 enemy 의 forced path.
  const blockedCells = walls.flatMap(w => w.cells);
  const path = aStar(entry, base.center, blockedCells);
  return path;  // 매 매 cell 의 mine + 매 turret cover.
}
```

### Layered ring (concentric)
```ts
function buildLayeredDefense(center: Vec2, levels = 3) {
  const layout: Building[] = [];
  
  // 매 매 ring
  for (let r = 1; r <= levels; r++) {
    const radius = r * 8;
    const turretCount = 4 * r;  // 매 outer 가 더 많음
    
    for (let i = 0; i < turretCount; i++) {
      const angle = (2 * Math.PI * i) / turretCount;
      const pos = center.add(new Vec2(Math.cos(angle), Math.sin(angle)).mul(radius));
      layout.push({
        id: `ring${r}_${i}`,
        type: r === levels ? 'sniper_turret' : 'machine_gun_turret',  // 매 outer 의 long-range
        pos,
        range: r === levels ? 25 : 15,
      });
    }
  }
  return layout;
}
```

### Damage-type-aware deployment
```ts
function placeResistancePlatforms(threat_profile: DamageProfile, slots: Vec2[]) {
  // 매 [[Arc 2 기술 및 2026년 연구 업데이트(March 2026 Research Drop)]] 참조
  const platforms: Building[] = [];
  
  // 매 매 expected attack type 의 counter
  if (threat_profile.burst > 0.3) {
    platforms.push({ type: 'support_reinforced', resists: 'burst', pos: slots.shift()! });
  }
  if (threat_profile.area > 0.3) {
    platforms.push({ type: 'support_insulated', resists: 'area', pos: slots.shift()! });
  }
  if (threat_profile.air > 0.4) {
    platforms.push({ type: 'support_aerojet', resists: 'air', pos: slots.shift()! });
  }
  
  return platforms;
}
```

### Honey pot
```ts
function deployHoneyPot(weakLookingPath: Cell[]) {
  return [
    ...weakLookingPath.flatMap(cell => 
      Math.random() < 0.7 ? [{ type: 'mine', pos: cell.pos }] : []
    ),
    { type: 'sniper_in_bunker', pos: weakLookingPath[0].pos.offset(2, 0) },
  ];
}
```

### Anti-bait positioning
```ts
function placeBaitProofUnit(unit: Unit, garrison_options: Vec2[]) {
  // 매 baiting 의 counter — 매 long-range + hidden + Hold Position
  const hiddenCover = garrison_options.find(p => isHidden(p) && hasLongRangeView(p));
  return {
    pos: hiddenCover,
    stance: 'hold_position',  // 매 don't chase
  };
}
```

### Defense effectiveness simulation
```python
def simulate_defense(layout, attacker_compositions, n_trials=1000):
    """매 매 attacker composition 의 defeat rate."""
    results = {}
    for comp in attacker_compositions:
        defeats = sum(1 for _ in range(n_trials) if simulate_attack(layout, comp).defender_wins)
        results[comp.name] = defeats / n_trials
    return results
```

### Layout iteration loop
```ts
function evolveLayout(initial: Layout, attacker_pool: Composition[], generations = 50) {
  let current = initial;
  for (let g = 0; g < generations; g++) {
    const variants = mutateLayout(current, n=10);
    const scored = variants.map(v => ({
      layout: v,
      score: average(attacker_pool.map(a => simulateDefense(v, a))),
    }));
    current = scored.sort((a, b) => b.score - a.score)[0].layout;
  }
  return current;
}
```

## 매 결정 기준
| 상황 | Layout |
|---|---|
| Generic | Square base + 4 corner turret |
| Anti-bait | Blitz base (long-range spread) |
| Vs heavy ground | Ring + AT specialist |
| Vs air | Layered AA + Nightwatch EW |
| Vs mortar | Spread + dispersion |
| New base | Square baseline → 매 evolve |

**기본값**: 매 layered + 매 cross-fire + 매 funnel + 매 platform-resistance + 매 anti-bait.

**언제**: 매 RTS / tower defense design. 매 base layout planning. 매 defense balance.
**언제 X**: 매 abstract / non-spatial game.

## ❌ 안티패턴
- **Single layer**: 매 break-through 의 fast.
- **No cross-fire**: 매 isolated turret 의 weak.
- **Symmetric obvious**: 매 attacker 의 read.
- **No funnel**: 매 mine 의 unutilized.
- **No anti-bait**: 매 [[Baiting]] 의 vulnerable.
- **All same damage type**: 매 single resistance 의 nullify.
