There is an option for using commanders as "regular units", in BKCII and FWC, but that's not in the older CWC!
Commanders are only attacked by indirect area fire & the odd command blunder (hence they need defence & hits values), but their attack ratings are only for AA fire - they represent the general AA fire your battlegroup can put out.
I view the commander stands as not just the commander and his staff, but the focus for the units logistics and communications etc. but others may differ
