You’re right in that our MTOE was exactly like any armored division other than some generalist slots were open to cav scouts as well as armor and infantry MOSs.
I’m referring to the older Divisional Cavalry Squadrons. I hear they have gone away but when we fielded the KW and the Longbow (I believe we were first to field both), we had I think 3 ground troops with brads and tanks, two air troops of KWs and the longbows went to 1-227 AVN which was out attack battalion. I don’t recall how many airframes each had though.
