Gel Bomb Rack

The Gel Bomb Rack is one of two attacks stored in an Advanced or Assault Aerotrooper's Remote Attack Pod. These stick to their targets until detonation, and cause a large amount of damage to Samus. High-velocity movement can remove them, however. Like the normal and Armored Aerotroopers, the Remote Attack Pod of bomb-wielding Aerotroopers also wield Particle Cannons, but instead of bombs they use a Helix Missile Pod.
