Yoshi Militia

The Yoshi Militia is a group of armed Yoshis, led by Bill the paranormal investigator (after first encountering each other in the "Dimension" saga). The Militia's origins are unknown, though they may have initially undergone secret combat training following one of the Mushroom Kingdom attacks in "Dimension Mix-Up." They possess high-powered rifles and shields, and even a battle-submarine, which they take to Yoshi's Island at the end of the War Above Earth to arrest Doctor Eggman. In addition, the Militia reappears during the  City Invasion  to assist Bill and Dib, by using rocket launchers against the Andor Genesis.
