Army soldiers are equally answerable to the POTUS as any Marine.  The President is the Commander in Chief over all branches of the military.  Do you think the Marines are the only fighters to be injured or die in combat?  I have sat in a C-130 awaiting transport just like any other soldier, don't think you have anything over other soldiers because you were a Marine.  I have just as much respect of a Marine as I do any other member of the Armed Forces.
