You need to read Col. Doug MacGregor’s critiques of our front line tanks. He says the biggest problem is that we are using jet turbine engines whose heat signature is easily identifiable from space sattellites and they can be knocked out by Russian anti-tank missiles. Not to mention they have to be run continuously to keep them operable.
Heat signature identifiable from space?
Ol' Dougie needs to lay off the vodka because the heat signature of the BS coming out of his mouth can be seen from Alpha Centauri.
They can be destroyed by Russian antitank missiles?
All tanks can be destroyed to one extent or another by missiles. With the Abrams however, the crew has a better than 90% chance of survival when hit unlike their Russian counterparts.
And it's a historical fact that the Abrams has survived hits by other Abrams tanks using the M829A1 "Silver Bullet" rounds during Desert Storm, as well as shrugging off hits from the much more powerful M829A3 "Super Sabot" during OIF during attempts to destroy disabled tanks to prevent them from being captured. The M829A3 BTW hits with a muzzle energy of 12.1 MJ or 8.9 million foot pounds of force.
On April 5, 2003 an Abrams was hit by a recoilless rifle and set ablaze (gear on the outside caught fire). After several failed attempts to put the fire out, it was decided to destroy the tank in place. Oil and .50 rounds were spread in the turret, the ammo doors were locked in the open position, a few thermite grenades were tossed in the turret, and another Abrams fired a HEAT round at it. After all that the tank was only disabled. The Air Force later dropped a bomb on it to destroy it.
So Russian missiles should be of no issue.
Run continuously to keep them operable?
Hardly
