Disagree. The enemy is in the battle and have personal experience of the details. They already know. It is us that do not know what is going on. The detail of what composition of units do not help the enemy.
\I am speechless. Are you serious?
It does help the enemy. Order of battle info is traditionally classified, and assignments certainly are. We employ entire MI sections to do nothing but ferret out the enemy's order of battle. It is significant. In short, just about everything the enemy does not know helps our side....that's part of the information battle.
