The reason IG can't use "marine" vehicles is because GW wants the factions to be separate but equal. SoB, Inquisition, Arbites, etc. all use Rhinos. It's a simple, rugged vehicle. The idea they had to make an even simpler version for the elite SA is butt fucking retarded and exists purely because someone didn't want SA sharing vehicles with marines. Same reason void troopers can't use Dreadclaws, even though Imperial Navy used them. Let alone anything else except armed civilian shuttles.
