A 40-year-old Active Guard Reserve First Sergeant assigned to the U.S. Army Reserve, Vallejo, California, on operational support orders died in a PMV-4 mishap 13 December 2023 in Stockton, California, at 1800 local. The Soldier was driving his van in the northbound lane when a tire detached from a concrete pumping trailer that was being towed by a 2019 Chevrolet pickup truck in the southbound lane. As a result, the trailer tire crossed over the guardrail and struck the front of the Soldier’s van. The California Highway Patrol (CHP) responded and pronounced the Soldier dead at the scene. The Soldier’s wife and three children were transported to the local hospital for minor injuries and discharged. According to CHP alcohol or drugs are not considered to be a factor.

Since FY19, the Army has lost an average of 35 Soldiers a year to PMV-4 mishaps. This mishap was the ninth fatality of FY24 and above the number of fatalities for the same time last year.
