Army Special Operations Command<\/a> will test new programmable swim vests after a Green Beret drowned during a roughly one mile swim in a quarry at Fort Campbell, Kentucky, while preparing for combat diver school in fall 2021.<\/p>\n\n\n\n

Staff Sgt. Paul Lincoln Olmstead was the second Green Beret to drown during dive-related training in 2021. An airman also drowned at his service\u2019s dive school in 2020 under circumstances similar to those of Olmstead.<\/p>\n\n\n\n

The new programmable vests \u2015 which are found on the civilian market \u2015 automatically inflate using carbon dioxide, or CO2, cartridges when a swimmer sinks below a set depth.<\/p>\n\n\n\n

That could have saved Olmstead\u2019s life after he went unconscious for unknown reasons and drowned Sept. 21, 2021, according to an investigation report obtained by Army Times through a Freedom of Information Act request.<\/p>\n\n\n\n

Investigators found that the \u201cprimary contributing factor\u201d to Olmstead\u2019s death was the \u201cinadequacy of the Aqualung Scout Swimmer Vest,\u201d which requires a drowning victim to be conscious to activate the CO2 cartridges in their vest.<\/p>\n\n\n\n

Investigators also raised concerns about other practices at 5th Special Forces Group\u2019s Maritime Assessment Course, which prepares soldiers for formal combat diver training.<\/p>\n\n\n\n

Although instructors running the course weren\u2019t negligent or in violation of any regulations, the risk mitigation measures \u201cwere not adequate to prevent SSG Olmstead\u2019s death,\u201d the report reads. \u201cSpecifically, allowing swimmers to swim without a buoy attached contributed to the instructors\u2019 and students\u2019 inability to locate SSG Olmstead after he had gone subsurface.\u201d<\/p>\n\n\n\n

Because Fort Campbell\u2019s Joe Swing Quarry is such a confined space, 5th SFG abandoned the use of buoys years ago, the report added. An unnamed individual from 5th SFG said in the report that the buoys risked causing swimmer entanglement.<\/p>\n\n\n\n

Previous deaths<\/h2>\n\n\n\n

Olmstead\u2019s death came months after another Green Beret, Staff Sgt. Micah Walker, drowned at the Army\u2019s combat diver school in Key West, Florida, and a year after an airman drowned at the Air Force\u2019s combat diver school in Panama City, Florida.<\/p>\n\n\n\n

None of the deaths involved breathing compressed gas or actual diving.<\/p>\n\n\n\n

Walker\u2019s death occurred during a water treading exercise, according to a dive official with John F. Kennedy Special Warfare Center and School. The official spoke with Army Times<\/a> days after the death on condition of anonymity due to an ongoing investigation.<\/p>\n\n\n\n

Safety swimmers had Walker out of the pool within three to five seconds of losing consciousness and slipping underwater, the official said in July 2021. He also disputed an Army Safety Center press release that called Walker\u2019s death a drowning.<\/p>\n\n\n\n

However, Army casualty records prepared this summer and obtained by Army Times via a Freedom of Information Act request stated that Walker\u2019s death was indeed a drowning.<\/p>\n\n\n\n

Maj. Rick Dickson, a spokesman at the John F. Kennedy Special Warfare Center and School, declined to comment further on the incident and said the investigation into Walker\u2019s death remains ongoing.<\/p>\n\n\n\n

A third recent drowning death in Panama City involving Air Force Special Tactics trainee Airman 1st Class Keigan Baker<\/a> occurred during an open ocean swim.<\/p>\n\n\n\n

Similar to Olmstead\u2019s case, investigators found no indication that Baker attempted to activate his CO2 cartridges before drowning, meaning he likely was unconscious. Also like Olmstead\u2019s case, investigators did not definitively determine why he went unconscious, though overexertion was one possible explanation.<\/p>\n\n\n\n

Wear and tear<\/h2>\n\n\n\n

After Baker\u2019s death in 2020, the Air Force Special Warfare Training Wing tested several commercially available automatic inflating swim vests, said wing spokesman 1st Lt. Xiaofan Liu.<\/p>\n\n\n\n

However, the wing ultimately decided not to acquire any of them.<\/p>\n\n\n\n

\u201cThe automatic inflating swim vests that the Special Warfare Training Wing initially tested were not designed for the continual wear and tear of the combat swimming conducted by trainees at the Air Force Combat Dive Course,\u201d Liu wrote in an emailed statement.<\/p>\n\n\n\n

\u201cThese automatic inflating swim vests were designed to save someone if he or she were to fall overboard from a vessel or aircraft … [and] didn\u2019t hold up well to the strenuous activities conducted by the trainees,\u201d Liu added, which include \u201copen water swims, water jumps from fixed-wing aircraft, hoisting patients out of the water, and fast-roping into the water.\u201d<\/p>\n\n\n\n

The Air Force did implement some changes, though, because there were problems found after Baker\u2019s death that also echo issues later found in Olmstead\u2019s case.<\/p>\n\n\n\n

The investigation into Baker\u2019s death found that instructors had special tactics trainees conduct a 2,000-yard open water swim without lines tethering them to swim buddies to ensure they didn\u2019t become separated.<\/p>\n\n\n\n

The Air Force now requires dive trainees to swim within six feet of a swim buddy at all times so a teammate can inflate a distressed swimmer\u2019s vest if they go unconscious. Trainees also must wear buoys during swims after it took hours to find Baker\u2019s body.<\/p>\n\n\n\n

Olmstead was also lost for some time underwater despite vigorous efforts by teammates to locate him.<\/p>\n\n\n\n

The investigation into Olmstead\u2019s death stated that he was close to finishing the quarry swim when he drowned. An instructor spotted Olmstead pass by his boat, then turned to observe other students.<\/p>\n\n\n\n

\u201cWhen he passed by, it was clear he was putting out incredible effort, typical of students sprinting the last couple hundred meters of the swim when close to cut off time,\u201d an instructor\u2019s witness statement reads. \u201cThe noise was typical of a soldier exerting great physical effort. It was not a sound of distress.\u201d<\/p>\n\n\n\n

When the instructor looked back at where Olmstead had been, he realized the student was missing. Instructors dove underwater and students waded in the shallow areas in search of him. The fire department and scuba teams were called in to sweep the quarry for him.<\/p>\n\n\n\n

Olmstead\u2019s scout swimmer vest was \u201cwithout defect\u201d and inflated as designed when investigators later manually activated the CO2 cartridges to test it out. Investigators determined that Olmstead most likely went unconscious before drowning.<\/p>\n\n\n\n

In addition to recommending new swim vests, the investigation called out how difficult it had been for soldiers to find Olmstead in a timely manner, which may have saved his life. Army special operations officials said they\u2019ve reviewed those findings and made changes.<\/p>\n\n\n\n

\u201cAt this time, the command is looking at acquiring the recommended vests for further testing and evaluation to determine suitability,\u201d said Maj. Russell M. Gordon, spokesman for 1st Special Forces Command. \u201cIn the meantime, the command took immediate action to mitigate risks by requiring students to wear an attached buoy for easy identification in the water, increase the number of safety boats, and increase the number of safety swimmers and also safety personnel outside the water.\u201d<\/p>\n\n\n\n

\u201cThe loss of SSG Paul Olmstead was an absolute tragedy, and he will always be a valued member of our Army special operations family,\u201d Gordon added.<\/p>\n","protected":false},"excerpt":{"rendered":"
