Modular Echeleon formation

Instead of a preset configuration, each unit type can be assigned a layer when in a stack.

The change should make the unit unable to move or perform any task for 1 hour. If the stack is attacked meantime on ground it cancels the change and attacks in standard preset. The stack cannot be split meantimem

Why this would be useful?

• Good Way to counter enemy stacks.

Example: the enemy has a stack with tank destroyers and mechanized infantry ( a formidable force against mbts) and the player has mbts and mechanized infantry. The player can put the infantry in front of the tanks so that the stack takes damage in a different way and survives better against the enemy.

• Making the battles longer.

In a naval battle the player can decide to put his cruisers behind and small ships in front, losing the smaller ships but staying in the battle for longer.
