In Battlefront 1 there is a limited supply but in Battlefront two there is unlimited. The IFT-X,IFT-T and the Rebel Combat Landspeeder have this. In Battlefront 2, the AAT also was equipped with this.
Rockets are also loaded into anti-tank unit such as the Heavy Trooper or even can be used as anti-infantry Wrist Rocket in the case of Super Battle Droid. A special variant of the rockets are the remote rockets, where they are highly controllable.
