The M60 tank was a main battle tank developed from the M48 Patton series, fitted with a 105mm main gun, a 7.62mm M240 coaxial machine gun, a 12.7mm M85 anti-aircraft gun, and operated by a four-man crew. In 1959, Chrysler received the first production order, and later that year production began at the Detroit Tank Arsenal, with the first production tanks completed in 1960. More than 15,000 were built by Chrysler, they first saw service in 1961, and production ended in 1983, though 5,400 older models were converted to the M60A3 variant through 1990. The M60 served as the primary battle tank of the U.S. Army and Marine Corps for two decades until it was replaced by the M1. Although criticized for its height and limits in cross-country capability, it proved reliable, underwent many updates, and saw its last operational service under the U.S. flag in Operation Desert Shield/Desert Storm, when the 1st Marine Expeditionary Force fielded 210 M60A1 tanks in the advance into Kuwait City. An M60 was later donated to Barry by the U.S. Army after Jody Gully sought a replacement for a World War I cannon formerly in the park, and the tank was transported from Fort Cluster, Michigan, to Barry on a 90ft. low boy rig at a total donated cost of $2,869.
