Spc. Mackenzie L. Shay, 20, a petroleum supply specialist with the 28th Infantry Division’s 128th Brigade Support Battalion, has died following a tragic training accident at Fort Indiantown Gap in Pennsylvania.
According to reports, Shay was participating in a routine convoy training exercise involving M1120 Load Handling System vehicles when the fatal collision occurred.
Authorities say Shay was driving one of two M1120 vehicles traveling in single file along a tank trail during a supply mission drill to collect ammunition dunnage. The lead vehicle reportedly came to a stop, and Shay’s vehicle collided with it from behind.
The impact caused the flat rack of the lead truck to penetrate the driver’s side cab of Shay’s vehicle. Fellow soldiers in the convoy quickly responded and pulled her from the wreckage, but she was found without a pulse and was pronounced dead at the scene.
Three other soldiers involved in the incident were transported to a hospital as a precaution and were reported not to have sustained serious injuries.
Army officials later confirmed that Shay’s death marked the first Ground Mobility Vehicle fatality of the fiscal year. The category has reportedly seen an average of nine training-related fatalities annually over recent years.
Spc. Shay’s death underscores the risks associated with military training operations, even outside of combat zones. Officials continue to review the incident as part of ongoing safety and training assessments.
She is being remembered by fellow service members and the broader military community for her service, dedication, and sacrifice.
Spc. Mackenzie L. Shay will be honored as her unit, family, and fellow soldiers mourn her loss and reflect on her service to the United States Army.
