Malmstrom Air Force Base officials released the name of the airman killed in a single-vehicle humvee incident on June 29.

U.S. Air Force Staff Sgt. Jorge Delgado, 37, was killed during the incident.

He was assigned to the 341st Security Forces Squadron at Malmstrom.

Three other airmen were injured in the incident and two first responders were injured while responding to the incident, according to Malmstrom officials.

Two of the injured airmen are in stable condition at a local medical facility and three were discharged, according to Malmstrom.

The four airmen were traveling on base in the humvee to their duty location at the time of the incident, according to Malmstrom.

“Team Malmstrom and our surrounding community grieve not only the loss of an outstanding airman, but a family member and a friend. As we help our impacted airmen and families, I urge us all to spend a little extra time checking in on one another, wrap our arms around those in need, and provide love and support, so we can keep enduring.  Wing One is committed to the safety and security of our members, and we will continue to stand strong during this time,” Col. Dan Voorhies, 341st Missile Wing commander, said in a release.

The investigation is ongoing.

Voorhies said during the July 2 City Commission meeting that the airmen were driving to the weapons storage area and the humvee “flipped.”

He said airmen from the Malmstrom Fire Department were injured while extricating airmen from the humvee.

Of the airmen sent to the hospital all but one had been released and the remaining airman was expected to be released within the next day or so.

Another Malmstrom airman was killed and another injured in a humvee rollover crash on Oct. 21.

Airman Alton S. John, 19, of the 341st Missile Security Forces Squadron, died Oct. 28, as a result of injuries sustained in the crash, according to the Montana Highway Patrol.

Both airmen in the humvee crash were transported to the hospital, according to Malmstrom.

According to the Air Force, an airman assigned to the 90th Missile Security Forces Squadron at F.E. Warren AFB in Wyoming was killed in a humvee incident in Colorado in September 2023.

The 20th Air Force announced the modifications to how the Humvees would be used in operations in December, according to Military.com.

“Last month, the 20th Air Force commander directed a modification to the way up-armored humvees are used in operations,” Col. Brus Vidal, an Air Force Global Strike Command spokesman told Military.com. “Although their use profile has been modified, missions will continue to utilize UA-HMMWVs when required.”

Military.com reported earlier this year that specific details of how humvee use would be modified for training or operations wasn’t provided by AFGSC, but Vidal said the humvees can still be used operationally when required.

According to AFGSC, between 2009 and Dec. 5, 2023, there had been 70 rollovers of tactical vehicles. Of those, there had been one serious injury and two fatalities over the same time period.

The humvees have been used for the nuclear security mission since “an off-the-shelf alternative doesn’t work during a hostile recapture/recovery scenario. Our nation’s nuclear weapons secure our homeland and our way of life; a vehicle incapable of ensuring their security is not an option,” according to AFGSC.

AFGSC is replacing some of the humvees with joint light tactical vehicles and the first nuclear security mission with those vehicles was conducted in 2023, according to the command.

“The JLTV is a modern and improved tactical vehicle providing better point of view, suspension systems, power and has modern safety features. However, no matter the vehicle, it is critical that our Airmen are trained to take the steps necessary to prevent an accident and understand the risks of not executing these steps,” according to AFGSC.

The command is looking at options to “ensure our airmen are safe and our nuclear weapons remain secure,” but there are a finite number of JLTVs in the Air Force inventory and training to operate the vehicles takes about 40 hours, according to AFGSC.

Tactical vehicle operators, including humvees, receive the following training, according to AFGSC:

• vehicle orientation and operation training
• vehicle crew concept training
• fatigue and human performance training
• gravel road training
• skid training
• route folder familiarization training
• basic driver’s safety training

“Dedicated training coupled with a culture of safety throughout our missile security squadrons are all geared toward minimizing vehicle mishaps,” according to AFGSC.

In December 2023, AFGSC said that the Air Force was evaluating the best options for tactical vehicles that is ongoing and will take time but nuclear security was a primary consideration.

AFGSC said that commanders were emphasizing a message of safety and reiterating convoy safety with civilian neighbors asking for locals to be cognizant of tactical vehicles and slow down around them.

There were a few tactical vehicle crashes on highways attributed to their low speed, according to AFGSC.
