SD:HS 129 B3 Tank Buster

 is a German Air unit. It is the most effective anti-tank airplane in the game, effortlessly piercing the front armour of all but the most well armoured Allied tanks in a few shots. In skies with German air superiority, the Hs 129 Tank Buster can absolutely wreak havoc on Allied tank columns.

Strategy

 * As far as tank busters go, the HS 129 is one of the most effective strike aircraft in its group. The B-3 is a class of its own, being essentially the A-10 Warthog of World War II. Although it has a limited ammo supply, it can destroy almost any enemy vehicle in a single attack run. Use it to root out enemy heavy tanks, particularly Rhinos and similar monsters that are a problem taking head on. However, remember that the Hs 129 takes a good, long while to rearm and as such every strike needs to be heavily considered.
 * However, it needs either air superiority or heavy protection. It's not designed for dogfights and relatively slow, allowing enemy dogfighters to run it down with relative ease. At any rate, unless you are confident that you have control of the air, keep it closer to your side of the front and be ready to evacuate it at a moment's notice while deploying your own fighters to chase the enemy away.
