Thats still disengenuous. In the case of the tactical aircraft for instance, I highly doubt they are including the carrier services provided by our CVNs and LHDs/LHAs whose operational and procurement costs are covered entirely by the Navy. Also, while they provided 31% of the ground forces that is almost entirely light infantry. We can debate how much it is still needed, but the Marine corps is not going to stand up well at all against a peer competitor fielding heavy weapons and mechanized arms. Things like tanks and the like are more expensive than light infantry and thats the Army's bag. In short, of course the Marines are cheap because their mission areas rarely cover the expensive portions of the overall defense budget.
