• Units move toward targets using pathfinding
• Units attack enemies when in range
• Unit state is synchronized across clients
• Unit health and damage system works correctly

Milestone Relation

Core gameplay mechanic for MVP combat system. Required for basic AI vs player battles and foundational for all future unit types.
