Other hypothesized risks from occupational exposure may manifest as symptomology not visible in the medical system or current standard of care. This study documents that service members in occupations that likely include repeated exposure to blast are at some increased risk for neurosensory conditions that present in medical evaluations. Other hypothesized effects (i.e., neurological outcomes) were smaller and were associated with acute exposure. The clearest finding was higher risk among blast-exposed MOSs for ambulatory encounters for tinnitus, with adjusted risk ratios of 1.19 (CI 1.03–1.37), 1.21 (CI 1.16–1.26), and 1.31 (CI 1.18–1.45) across career time points. These two groups were compared in hospitalizations, outpatient visits, pharmacy, and disability ratings. Records from a population of 50,254 service members in MOSs with a high likelihood of occupational blast exposure were compared to records from a matched cohort of 50,254 service members in MOSs with a lower likelihood of occupational blast exposure. We hypothesized that populations exposed to blast by virtue of their military occupation would have poorer global medical outcomes than cohorts less likely to have been occupationally exposed. The purpose of the present study was to examine medical records for evidence of blast-associated effects that may have clinical significance in current standard of care. Despite the challenge, occupational blast-associated effects in humans are emerging in ongoing research. ![]() ![]() Instead, effects, if any, should be expected to be incremental in nature and to vary among individuals of different susceptibilities and exposure histories. Any gross effects from such occupational blast exposure on health or performance should be expected to have been already identified and addressed by affected military units through changes to their standard training protocols. Their bravery and skill is inspiring.The study of effects associated with human exposure to repeated low-level blast during training or operations of select military occupational specialties (MOS) challenges medical science because acute negative effects that might follow such exposures cannot be expected to be clear or prevalent. They willingly accept they are high value targets of the enemy hoping to silence their guns. Military cannon crews spend months in the field, often far from home. Students must be pretty good at math and, like everything nowadays, capable of using a variety of computer devices. Students learn how to program and fire their M777 “Triple Seven” Howitzers, maintain both their weapon and support vehicles, and spend many hours working at night under intense field conditions. To become a military cannoneer, a candidate must pass 10 weeks Basic Training and 7 weeks of Advanced Individual Training at the home of American artillery, Ft. These troops load and fire howitzers, set fuses and charges on multiple munitions, and must make split second decisions, often while under fire themselves. Today, Army Cannon Crewmembers (MOS 13 Bravo) are responsible for firing howitzers in support of infantry and tank units during combat. The term Howitzer comes the German word “Haubitze” or basket and refers to a cannon with a shortened barrel and a breach shaped like a funnel increasing accuracy and portability. artillery came of age in the 1830’s when smaller, lighter cannon with longer range were produced, the most famous being the Model 1841 Mountain Howitzer. ![]() ![]() Artillery Cannon Crewmembers.įor over two centuries, American artillerymen have delivered close fire support for infantry units like these saving countless lives and deciding many battles. Their survival depends on the skill and bravery of U.S. (July 31, 2022): These are the most chilling words a soldier can hear crackle over the radio “We are being overrun!” A squad is pinned down with multiple wounded, unable to move as the enemy closes in. American Cannoneers provide close fire support for infantry units when lives are on the line.įt. Army Joint Multinational Readiness Center at Hohenfels, Germany.
