I was able to run 4 hours with my brother in law (driver) and son 15 (gunner) and daughter 12 (loader) and myself (tank commander) in a real M1 tank simulator. I can say that that tank is super easy to operate. It’s tactical training crews need. I’m sure killer drones messed up the modern battlefield.... Every one is going to figure out how to counter act them.
I used to test antennas on a large platform ground rotatotr and we once got an M1 for a month to test. We were testing the MMW BCIS system antennas as the time. It was neat to ride in.
