The tank shoots the jet like a normal shot. When the jet reaches its highest altitude it shoots 4 rockets one by one. Each rocket locks in the enemy who is nearest to the Jet at the time the rocket is shot, and if there are no obstacles in the way the rocket hits that enemy. If you manage to make the jet crash into a tank, it deals damage depending on the distance it has traveled before crashing. If launched in a 90-degree angle without wind, the jet will always fly to the east of the field. If the missile gets hit by a bumper at flight it will try to correct itself and lock on the tank again. Depending on the situation it will just hit the ground as it tries to lock onto the enemy.
The mechanics of Heavy Jet are identical to those of Fighter Jet, with the exception of the Jet's explosion radius being bigger and increased damage for every rocket.
Similarly to the portals of Portal Gun and the hovering mechanic of Hover-Ball, Jet's flight is not a perfectly horizontal line. If you look very closely, you can see that it falls very slowly.
