Is there a way to pull a unit/brigade out of a division without breaking up the whole division and the reforming it minus that one unit?
I don't think so. Because of this, I tend to leave damaged units in the division and rest the whole division.
Any other tips on how to get replacements to elements? I have been pulling badly depleted brigades out of divisions and back to a friendly structure.
Like I said, that can mean a lot of clicking and micromanaging that might be unnecessary. The recovery rate is based on the structures in the region (Depots are the fastest and give the max replacement rate). If you are already in a region with cities, forts or depots, then just rest them where they are, no need to leave unless you are facing imminent attack. They cannot access replacements if they are moving, so sometimes recovering in place is faster than rotating them away to a better structure. Information on recovery rates is available in the AGEWiki
and the AACWiki
, although they do not match each other. It is possible that replacement rates are different for CW2 and that both sites are inaccurate for our purposes.
They will still draw replacements in defensive posture; this may sometimes be advisable. They recover cohesion faster when set to passive posture.
Units inside structures in passive posture receive priority for replacements (if there are not enough chits to go around these will get the chits available) but you will still draw replacements if the unit is outside the structure as long as you have enough available.
