Some of Massi's units do seem to have issues. USSOCOM 75th Rangers, for example, have motorized groups defined, but can't spawn with ALiVE (the units spawn but the vehicles are invisible the last I checked and I'm positive is added the vehicles PBO correctly. Haven't checked the vehicles version on Workshop though). I reported the issue over on his Workshop thread, but he's not been active in a bit.

I'd say just go ahead and report the issue and see if he can look through it for a future update.
