I'm currently reading the book Carnivore which is about a cav scout soldier and his units fight during the invasion of Iraq. The author writes about engaging T-72 tanks with the Bradley 25mm depleted uranium or DU rounds and killing the tanks. My question has to do with the Ground Combat Vehicle and arming it with a 25mm cannon and not something bigger. Could these type of experiences in Iraq had something to do with the idea of arming the GCV with a 25mm cannon? Or, is it simply about going with the status quo? Do U.S. Army armor thinkers believe that in the future the type of armor we are most likely to face will be Soviet design like the T-72 and the DU rounds will be sufficient to destroy the vehicles. The author did say that if the T-72 hit his Bradley with its 125mm the crew would be toast - no suprise there.
