Extensive training is required for a modern M1 Abrams crew. It's not just point and shoot.
Extensive training...
I disagree. I was lucky to experience 4 hours in an M1 simulator with my son, daughter and brother in law. After about 15 minutes of training at each position you could operate it. It was very much point and shoot. It’s very used friendly. I say a good week of training and you have a compatent crew. They need a good tank commander who knows tank tactics and they need a strong will to fight cause getting shot at isn’t fun.
