Mack M-123 series

In 1955 it became evident the replacement of the M-20M-26 and M-26A1 tank transporters that had given such valuable services to the American forces since WWII. The Mack company designed a 6×6 10-ton truck tractor under designation M-123. This vehicle could also perform recovery tasks thanks to a dual winch installed behind the cab. Between 1955 and 1957, 392 trucks of the M-123, M-123C and M-123D variants were delivered to the US Army. Between 1965 and 1968 Mack and Consolidated Diesel companies built the most numerous model of the whole series, the M-123A1C. A total of 3,608 vehicles of this variant were built and a single winch and a new Cummins diesel engine were installed. In 1968, all the M-123 / C / D tractor trucks were converted to the M-123A1 model, which mounted a double winch and a Cummins diesel engine. The M-123 used the M-15A1 and M-15A2 heavy loads semitrailers and the M-172 and M-172A1 semitrailers for loads up to 25 tons.
