The Hidden Dangers of Explosive Weapons Training in the Military

Recent studies have shed light on the alarming connection between explosive weapons training in the military and potential brain injuries caused by blast waves. While it has long been assumed that being a ‘safe’ distance away from the blast zone protects individuals, a new study suggests otherwise. Researchers have found that exposure to repetitive, low-level blasts, such as those from hand grenades, can lead to a leaky gut. This phenomenon is linked to decreased cognitive function, as the permeability of the gut is controlled by neurons. The symptoms observed in individuals exposed to these blasts align with mild traumatic brain injury (TBI), including abdominal pain, gastric issues, and constipation. The leaky gut condition coincides with a reduction in specific gut proteins, which are essential for maintaining the integrity of the intestinal walls. An increase in gut permeability can result in bacteria leaking into circulation, potentially causing havoc on the body’s systems and contributing to conditions like Alzheimer’s disease and schizophrenia.

A study conducted by neuroscientist Qingkun Liu and his team in the US examined 30 male participants, most of whom were combat engineers. Among the participants, 18 reported existing mild traumatic brain injury from direct blunt force trauma rather than blasts. The researchers collected blood samples from the participants shortly before and after wall-breaching exercises, where they stood 12 meters away from the blast. The results were concerning, showing increased bacterial translocation in the participants’ blood circulation post-blast exposure. Additionally, the protein biomarkers associated with gut leakiness were disrupted. Participants reported symptoms like headaches, dizziness, difficulty concentrating, and cognitive slowing, which gradually lessened over 12 hours. These findings, while observational, suggest that blast-related intestinal permeability may be linked to decreased cognitive functioning, highlighting the significance of the gut-brain axis in blast-related injuries.

Implications for Military Personnel and Veterans

The implications of these findings are especially critical for military personnel and veterans who undergo explosive weapons training. A recent investigation revealed that even low-level blasts from activities like shoulder-fired rockets could have long-lasting effects on brain health. Shockwaves generated by blast waves can lead to brain damage that mimics post-traumatic stress disorder, often being mistaken for other conditions. Past cases of blast instructors experiencing fatigue, memory issues, and confusion have raised concerns about the lack of protective measures in place. Despite mounting evidence linking blast exposure to brain damage, there is a notable gap in awareness and action to safeguard individuals from such risks.

As researchers emphasize the need for additional studies to better understand the impact of blast waves on gut health and cognitive function, there is a growing call for protective measures to be implemented in military training settings. The bipartisan group of US Senators demanding accountability from the US military underscores the urgency of addressing this issue. It is crucial to recognize that even blasts deemed ‘safe’ by current standards may pose risks to individuals’ health and well-being. With ongoing research shedding light on the hidden dangers of explosive weapons training, prioritizing the safety and health of military personnel, instructors, and veterans becomes paramount. Efforts to raise awareness, encourage further research, and implement preventative measures are essential in mitigating the adverse effects of blast exposure in military settings.
