The United States Marine Corps is getting rid of tanks. This is quite controversial, but the recent evidence from the Ukraine - Russian war indicates that tanks are sitting ducks, destroyed by low cost drones and man packed anti tank missiles. It seems likely that tanks are going the way of World War II Battleships - outmoded by technology. Smart weapons have made them outmoded.
Just in case this is wrong I think the Marine Corps should mothball it's tanks, and keep its two Reserve Tank Battalions. Low cost insurance.
