Often after a furious campaign I will review my command stacks for reorganization. I find divisions, generally assigned to a Corp, with elements eliminated. For example a division starts with 2 INF elements and an ART element after a series of battles the ART element is left and the INF elements are not even listed in red. The problem is the unit is still a division with a command point requirement of 6 so it is highly inefficient to keep this division.
Will the elements return if I retreat these divisions to a depot and leave them to rest? Or is the division shattered and now useless (or nearly so due to the cost for command)?
Thank you
