Noted for its mountain goat-like off-road performance, the "Gamma Goat” was nicknamed after Roger Gamaunt who invented its powered articulated joint. Designed in the late 1950's by Chance-Vought Aircraft, the M561 could be set for two or six wheel drive, and could use its tires to propel itself in amphibious operations. Bilge pumps were standard issue to deal with minor water on board but drivers had to remember to close the hull's drain openings before swimming the vehicles.
