M551 Sheridan

Airborne!

"Always make the enemy think you know more than you really know" ~ Gen. Phillip Sheridan

The M551 Sheridan was an American Light Tank Airborne Assault Vehicle that was rushed into service to meet the demand for armored vehicles in Vietnam. Unique for its time, the 152mm main gun was able to fire anti-tank guided missiles, although these were not used in Vietnam, and was ultimately replaced with the more ubiquitous BGM-71 TOW missile launcher. Instead, the Sheridan was primarily an infantry support vehicle, using its low-velocity cannon to fire HE Shells.

The Stats

The Sheridan is the only tank that you can take as part of the Huey air assault list, since it was the only tank you could throw out of the back of airplane where the airborne needed it most.

The M81 152mm gun is an interesting weapons system. At close ranges (out to 16") it uses a HEAT shell with AT 21 and a firepower of 1+. Yes, you can one shot T55s, and with the brutal rule infantry and other units without an armor save have to reroll their successful saves. Unfortunately, you only have a ROF of 1, though it is both moving and halted, and with a stabilizer you don't get +1 to hit for moving. For ranges in exes of 16" (because you physically cannot shoot it less than that) you can use the MGM51 Shillelagh (Shill-lay-lee) Guided Missile. The Shillelagh is AT 22 firepower 3+ missile that can smack targets out to 48" away. However you can't fire the Shillelagh on the move.

Now since the difference between AT is negligible, and the firepower disparity is the difference between killing a target 2/3rds of the time, and killing it every time, you might wonder why would you ever use the Shillelagh.

EAT THIS IVAN!

Served as a machine gun pill box in vietnam its ATGM was buggier than an Iphone and never destroyed anything other than a few pill boxes in Iraq. Its gun was 152mm every time if fired the vehicle bucked backwards and all the fucking electronics had to go through a full reboot. Hilariously, when the Sheridan was retired from active service, the NTC picked up a couple and dressed them up as soviet block vehicles (T-72s, T80s and BMPs) to help train US service men in identifying possible enemy tanks.
