Even after years of testing the M151 had a major problem with roll-over especially when cornering. This vehicle saw its first combat in the Vietnam War and lasted well into the 1980s when it was replaced by the AM General HMMWV. The M151A2 arrived in 1970 with an improved rear suspension which improved the cornering problem of roll-over but didn’t eliminate it. The USMC continued to use a variant of the M151 until 1999 because of its ability to be transported inside a CH-53 helicopter.
