UNDERSTANDING SUBCONCUSSIVE BLAST EXPOSURE IMPACTS

that cleared the sinuses. To mitigate these effects, we tried to line up as close to the shooter as possible.

As we are exposed to blast pressure when we are working with explosives to breach (gain entry to a room or compound), when demolishing enemy equipment, or while initating an ambush, we use an equation that accounts for the net weight of all explosives being used and provides the minimum safe distance needed for standoff.

To mitigate some of our exposure but still get the repetitions, we rotate through individuals who stand in the front of the line. Also, when possible, we use smaller charges on door simulations to practice the repetitions without the effects of a full-size charge.

One method being tested to evaluate overpressure blast exposure is measuring levels of various proteins in blood

samples. For example, levels of amyloid beta peptides in the serum have been shown to increase within 45 minutes of blast exposure. More studies need to be completed to determine how this could be helpful in evaluating TBIs.

Studies are ongoing considering the potential hazards of TBI for current weapons training. Operators should continue to mitigate risk. For example, range safety officers should stand as far back as possible while still effectively evaluating a shooter’s performance. When shooting 50-caliber weapons, the spotter should line up as directly behind the shooter as possible while also increasing the space between the shooter and spotter.

Evaluations should be done to assess the amount of overpressure an operator in certain rates and military occupational specialties could potentially experience in their career.
