The numbers are in, and they’re concerning—suicide rates within the United States military are still on the rise despite years of efforts to prevent this tragic outcome.

According to the Department of Defense’s (DoD) Annual Suicide Report, issued on Thursday, the calendar year (CY) 2023 saw a modest increase in suicides across all services, with the Army and Air Force experiencing particularly worrying rises.

While the Navy had a slight decrease in CY 2022, CY 2023 saw its highest suicide rate since CY 2019, and the Marine Corps continues to bear the highest rate overall.

Suicide Rate in the Military

In CY 2023, the military lost 523 service members to suicide, up from 493 the year before. This figure is even more alarming when you break it down by branch.

The Army and Air Force were hit hardest, with suicides in those branches rising significantly.

For the Army, this spike is especially concerning, as it follows years of increased rates that show no signs of slowing down.

The Navy, too, experienced an increase in suicides, bringing the rate to 21 per 100,000 sailors—marking the highest it’s been since CY 2019.

Meanwhile, the Marine Corps, which has consistently had the highest suicide rate in recent years, saw a slight drop, but it remains at a staggeringly high rate of 35.9 per 100,000.
