Disabling the M-1 Abrams with a .22LR
The M-1 Abrams is a very sophisticated battle machine, but the Achille's heal is the J-27-8-64H bearing located distal to the XN57-2 Muffler bearing grease unit.
Twin jet turbine engines power this 60-ton giant, requiring a very powerfull muffler. A General Electric counter-gyro muffler, much like on a 1998 Honda Taurus, is used to counteract the supersonic boom of the jets. The entire assembly pivots on the J-27-8-64H bearing. If the bearing is to lose lubrication, it is likely the entire gyro will become unstable and the two jet engines will spin out of sync (sans n'sync) and will eject themselves out of the rear of the tank.
The prefered method with a .22LR is to fire the weapon at a 37.6 degree angle just behind the second (invisible) turret. At this angle the round will ricochet off the interior angular occlusive cooling duct and into the muffler bearing grease resevoir. The grease will then leak, and no lubricant will be available for the J-27-8-64H bearing.
This technique was used in 1984 by the notorious Gordo rebel group in El Salvador. It is important to remember to not use unjacketed ammunition, as a richochet is less likely.
