The Heavy Trooper is a term given to the Clone anti-vehicle specialists. They only appear in the Star Wars: Battlefront series.
They appear in the original Star Wars: Battlefront (where they were called ARC troopers), Star Wars: Battlefront II and the Renegade Squadron. They’re identical to all other anti-armor classes and have the same equipment. They possess considerably more health then other classes, but also have the slowest movement speed.
Their primary weapon is a shoulder-mounted missile launcher, which fires slow-travelling blue-hued missiles (up to 8 can be carried at any given time). These missiles will instantly destroy most turrets and STAPs, but many shots are required against the numerous Droid tanks. Using the “lock-on” mode with the missile launcher will highlight the weak spots on the vehicles, where all shots will deal increased damage. After hitting them 3 times, you will be able to use 5 guided rockets with it: they don’t replace the regular missiles but are used alongside them as a tertiary fire mode, with. These missiles can be slowed down or accelerated much like the starfighters; they much easier to aim when they’re slowed down but are only worth it at highest speed, when they explode with high damage over a large area. As such, they should only really be used at large, open maps where you have time to boost them to full speed.
Their secondary weapon is a regular blaster pistol with infinite ammo but high overheat that can be replaced with the Award precision pistol after killing 6 people with it. They also have two regular Thermal Detonators and 3 mines. The latter are very, very powerful, killing everyone and destroying full-health tanks in 3m radius. Even though they take about two seconds to activate, they should never be set up in the heat of combat, as the blast is guaranteed to kill you alongside the enemies (unless, of course, you have turned the friendly fire off or are about to die anyway). Mines don’t take any damage from regular weapons, but will be destroyed by the explosives. The Engineer classes will also safely walk past them and can destroy them with fusion cutters.
AI-controlled Heavy Troopers almost always fight with pistols, very rarely using their missile launchers against vehicles, heroes and on large maps over the long distances. They will use grenades against vehicles and in tight spots as often as everyone else, but only set up mines on a handful of maps. They can also roll away from Thermal Detonators or particularly heavy fire. Some of them will occasionally use the guided rockets, the only case of AI unlocking the AWARD weapons.
