Revenge of the Sith - Swamp Speeder. The light, antigravity repulsorlift ISP Speeder is used by Clone Troopers to bolster the wookiees' defensive forces. This highly maneuverable attack vehicle is effective against enemy infantry, gunships and tank droids. This Swamp Speeder differs from the 2005 Swamp Speeder by having a green color scheme, painted on "dirt" and the troopers colors are now more accurate.
