M1A2 is the more advanced model.
M1a2 stats: 125mm smoothbore cannon,1500 hp and manual loader
this answer is not ture for many reason one. the m1a1 is a out dated verison of the m1a2 and the most advanced tank in the world is the British Challenger 2
M1A2 and M1A1 Abrams. There MIGHT still be some M60A3 tanks in use with the National Guard.
Chuck Norris invented the M1A1 Abrams tank after one of his movies because he had nothing else to do.
That information is classified.
The M1 was 60 Tons M1A1 63 M1A2 69.54
Of course.
M1A2 Abrams. 68 tons of steel.
Depends on what tank you are referring to. The M1A2 Abrams tank has 120 mm (4.72 inches) of armour.
The biggest tank in the world would probably be the US M1A2 Abrams main battle tank.
M1A1 Abrams....yeah.....it's Americas MBT(Main Battle Tank)
It is among the most advanced in production, though it's not the only such tank in existence.
