I. Core Principle

Naruto combat is three-dimensional and mobile.
Formations are fluid, not rigid.

Shinobi rarely stand side-by-side unless forced.
Spacing, angles, and sightlines matter more than adjacency.

AI must think in terms of:

• Distance

• Elevation

• Protection arcs

• Engagement lanes

• Escape vectors

II. Standard Spacing Rules

In open terrain, balanced squads maintain:

• Striker: 10–20 ft ahead of main body

• Tank: Center of formation

• Controller: 10–20 ft lateral offset

• Support: 20–40 ft behind front line

• Sensor: Slightly elevated or mid-rear

This prevents AoE collapse and allows role protection.

III. Formation Types (Descriptive)

1. Diamond Formation (Balanced Readiness)

Structure:

• Striker stands slightly forward of the group.

• Tank anchors the center.

• Controller and Sensor take flanking positions left and right.

• Support stands behind the Tank at safe distance.

The group forms a loose diamond shape.

When Used:

• Unknown enemy strength

• Mixed terrain

• Defensive scouting

Strength:

• Protects Support

• Flexible response in any direction

Weakness:

• Vulnerable to large-radius AoE

AI Behavior:

• Striker probes first.

• Tank engages if pressured.

• Controller adjusts terrain.

• Support remains mobile but guarded.

2. Spear Formation (Forward Pressure)

Structure:

• Striker leads at the tip.

• Tank follows directly behind.

• Controller and Assassin operate on either side of the Tank.

• Support trails furthest back.

The squad forms a narrow forward column.

When Used:

• Assault missions

• Breaking enemy line

• Target elimination

Strength:

• Strong forward momentum

• Concentrated burst potential

Weakness:

• Flanks exposed

• Rear vulnerable to stealth attack

AI Behavior:

• Striker forces engagement.

• Tank absorbs counter.

• Controller narrows battlefield.

• Assassin looks for side openings.

3. Shell Formation (Defensive Hold)

Structure:

• Tank stands at the center.

• Controller(s) position slightly forward-left and forward-right.

• Support and Sensor remain directly behind Tank.

• Striker roams short radius around perimeter.

The team creates a defensive arc around its core.

When Used:

• Protecting VIP

• Waiting for enemy approach

• Holding territory

Strength:

• Difficult to penetrate

• Protects fragile members

Weakness:

• Slow repositioning

• Predictable footprint

AI Behavior:

• Tank draws focus.

• Controller blocks lanes.

• Support remains untouched.

• Striker counters any breach.

4. Split Assault (Advanced Teams)

Structure:

The team divides into two 2-person elements.

Example:

• Element A: Tank + Striker

• Element B: Controller + Support

They operate 30–60 ft apart.

When Used:

• Against larger teams

• To divide enemy attention

• In dense terrain

Strength:

• Creates cross-pressure

• Forces enemy to split

Weakness:

• Dangerous if one element collapses

AI Behavior:

• Controller manipulates terrain between elements.

• Striker pressures weak targets.

• Support rotates if needed.

Only Jōnin+ teams use this effectively.

IV. Terrain-Based Adjustments

Formations change based on environment.

Forest

• Striker uses trees for vertical flanking.

• Sensor elevates.

• Support stays near trunk cover.

• Controller manipulates ground or roots.

Spacing increases due to visibility obstruction.

Urban

• Tank holds chokepoints.

• Controller blocks alleyways.

• Assassin uses rooftops.

• Support hides behind walls.

Tighter spacing, more vertical play.

Open Field

• Spread formation to avoid AoE.

• Striker stays mobile.

• Controller attempts to create artificial terrain.

Wide spacing is mandatory.

Water Terrain

• Water users gain advantage.

• Tank holds shallow ground.

• Striker avoids deep water unless specialized.

• Controller attempts current manipulation.

V. Formation Breaking

High-level AI intentionally disrupts enemy formation.

Common tactics:

• Knockback to separate Tank and Support.

• Terrain wall between Striker and Controller.

• Genjutsu on Sensor to remove awareness.

• Assassination pressure on Support.

Breaking formation is often more important than dealing damage.

VI. Rotation Logic

If one member falls:

• Tank down → Controller shifts center.

• Support down → Striker disengages faster.

• Controller down → Team spreads out.

• Sensor down → Team becomes cautious.

Jōnin+ AI adapts within 1–2 rounds.

Genin AI does not adapt.

VII. Retreat Formation

Proper retreat:

• Tank disengages last.

• Controller blocks line of sight.

• Striker uses clone distraction.

• Support leaves early.

Retreat must involve:

• Cover

• Misdirection

• Vertical repositioning

Straight-line retreat = poor AI.

VIII. Kage-Level Geometry

Kage do not use formations.

They define the battlefield.

Examples:

• Flooding terrain

• Raising stone plateaus

• Creating mirror domes

• Reshaping forest

At this level:
Formation is replaced by domination.
