STAP-2

The STAP-2, which was also known as the Heavy STAP, was developed for the Trade Federation prior to the Invasion of Naboo.

Characteristics
It sported larger laser cannons and a missile launcher. Several STAP-2 vehicles were seen to be modified with shield generators. The Heavy STAP was used to scout dangerous enemy territory and to eliminate retreating enemy forces.

Its disadvantages included less agility than the standard STAP-1 and difficulty in crossing certain types of terrain, including rivers.
