Model Animation Questions

[7heDubz]

I haven't tested animations that imitate physics, but i have successfully imported animations that consisted of rotating and moving whole meshes. In either case Maya was required, even though i made the animations in Blender.

Rotating and moving... So bones are not required for the animation to take effect in game, Will the animation loop constantly?
(My guess is yes because of the way the grunt (Or brute? i mix up the names..) moves inside of the level editor, I just want to make sure
