Which is the reason why I strongly believe that a Rhino has at most one marine (as commander) and one servitor (as driver). It is also not at all unheard of, that tank-commander would serve as gunner (in case of Predators/other MBTs) and when we think it more... I honestly can not think a mighty Space Marine loading up Vindicator shells into some big cannon, resulting that in Vindicators there would be at best 2 Marines (commander and gunner while loader and driver would be servitors) and when it comes to Predators... autocannon is belt-fed, it requires no further loading (at least in my experience of IFVs) in action and if it happens to use Lascannon... well changing cabel from one pack to another doesn't seem that hard either. Can't see why there would be more than one (commander) marine in Predators.
