Added crouch, prone, and squad formations
Infantry can drop to a knee or the ground for less damage, and a squad can be ordered into a line, a loose group, or a tight one.

Crouch and prone are timed poses with real damage reduction: about thirty percent on a knee and fifty percent flat. Standing is required before a travel order, so a prone squad does not slide away while lying down.
Formations are tight, loose, and line, with three spread distances. Double-time is a double-click that runs at half again the walk speed and holds fire until the run ends.
“A formation matters when the soldiers in it can actually lie down.”
The body is one connected rig. Legs, arms, and the rifle stay attached through the pose, and the torso can aim while the legs face another way. Blocked soldiers stop walking instead of pushing through each other.
Rockets got slower and heavier. A blast can knock nearby infantry down for a short recovery, and crouched soldiers resist that more than standing ones.
