An expeditionary Marine Corps means a lighter Marine Corps.
But what do you do when you need armored protection to operate deep....to seize an objective because air defenses will not allow a heliborne assault?
You send a mechanized force to blast through defenses and maintain the momentum of your landing on the beach.
But wait! The USMC is rapidly divesting itself of armor! Tanks is being whittled away and our AAVs are as old as dinosaurs. The answer? You use call on your buddies in the Big Army to land an Armored Brigade Combat Team to carry the torch that you just handed them after DOING YOUR JOB and taking the beach.
Jointness doesn't mean operating together, it means staying in your lane and not duplicating capabilities found in the other services. The ABCT is what the US Army can contribute to the fight IF Big Army gets moving.
