"The Mack M123 (G792) was a 10-ton 6x6 semi-tractor introduced in 1955; the Mack M125 was a heavy cargo truck version of the M123. The M123 was used to tow tank transporter trailers while the M125 towed field artillery pieces.
"In 1949 the US Army set a requirement for a family of extra heavy-duty 10-ton (9,072 kg) off-road load rated 6x6 tactical trucks. Mack's design, influenced by their WWII era NO, was chosen. Designed as an entire family, only the semi-tractor and cargo/prime mover were built. 392 M123s were built between 1955 and 1957 and 552 M125s in 1957 and 1958.
"In 1965 CONDEC began building 3188 diesel powered M123As, Mack began building 420 in 1968. In 1969 Mack then upgraded 210 gas engine models to diesel power.
"With the Army using more self-propelled artillery, the need for prime movers was reduced, no follow-up orders for M125s were made.
"Both M123s and M125s saw service in the Vietnam War. M123 tractors remained in Army service into the 1990s.
"In addition to the US Army, the M123 was used by the U.S. Marine Corps and exported to U.S. allies in such countries as Australia and Spain." ~ Wikipedia
