Designed for use on improved roads it does not have a driven front axle. HistoryThe M915 is the namesake and basis of a tactical truck series, although it is not tactical itself. It is a commercial type conventional 6x4 rear wheel drive 14-ton semi-tractor designed for use on improved roads. A powered front axle and other tactical equipment are not needed for this role, allowing a lighter and simpler truck. It shares the engine, transmission, cab, and some components of the other trucks in the series.{{sfnp|TM 9-2320-363-10|1997|p=1-15}} The more specialized trucks in the series are the M916 6x6 all wheel drive 14-Ton Light Equipment Transporter (LET) tractor with rear winch; M917 8x6 20-ton, 12 cubic yard Dump Truck; M918 6x6 22.5-ton, 1,500 gallon Bituminous Distributor; M919 8x6 22.5-ton, 8 cubic yard Concrete Mixer; and M920 8x6 20-ton Medium Equipment Transporter (MET) tractor with rear winch, all of which are employed in Engineer Combat Support and Construction units. The M915 and follow on M915A1 were a Crane Carrier Company design based on CCC's Centaur commercial tractor, built under contract by AM General between 1978 and 1982. The 1990 -A2 upgrade was actually a completely different truck: a Freightliner Trucks design with a different engine and transmission, hood and cab. Older models were upgraded to -A4 standard with a new cab and frame that used the original truck's components. Starting in 2009 M915A3s were upgraded to the armored -A5 standard. Engine and drivelineThe M915 has a {{convert|855|cuin|L|1|abbr=on}} Cummins NTC 400 developing {{convert|400|hp|kW|abbr=on}} at 2100rpm and {{convert|1150|lbfft|0|abbr=on}} of torque at 1500rpm. The M915A2 had a {{convert|775|cuin|L|1|abbr=on}} Detroit Diesel DDEC II developing {{convert|400|hp|kW|abbr=on}} at 2100rpm and {{convert|1400|lbfft|0|abbr=on}} of torque at 1200rpm. Both are turbocharged inline 6 cylinder 4-stroke diesel engine, the DDEC II is also intercooled.[2]{{sfnp|TM 9-2320-363-10|1997|pp=1-17, 1-18}} The M915 has a Caterpillar 16 speed semi-automatic transmission, the M915A2 a Allison HT-470 4-speed automatic.{{sfnp|TM 9-2320-363-10|1997|pp=1-17, 1-18}}{{sfnp|TM 9-2320-273-10|1980|p=1-19}} ChassisA conventional ladder frame has a front steering axle with a {{convert|12,000|lb|abbr=on}} weight rating and tandem rear axles with a {{convert|40,000|lb|abbr=on}} weight rating.
