The three serious accidents in the US military in just one month make people ponder: What caused these tragedies to happen?On the 14th, according to the American News Times, on December 12, a Marine Corps amphibious combat vehicle overturned at the Marine Corps Training Base in Pendleton, California, killing one Marine and injuring 14 others. The accident has once again raised concerns about the frequent accidents in the US military. 
However, this is not the only recent tragedy of the US military. Just a day earlier, a US Air Force F-16 fighter jet crashed while training in South Korea. Previously, a CV-22 "Osprey" tiltrotor also crashed near Japan, resulting in the death of all eight people on board. These accidents not only caused people, but also brought huge economic losses. 
In fact, accidents with amphibious combat vehicles of the US military are not uncommon. In 2022, there were at least three non-fatal rollover accidents in these vehicles during water training. And in 2021, the 15th Marine Corps Expeditionary Unit also had an amphibious combat vehicle sinking accident in the sea, resulting in the death of 8 Marine Corps soldiers and 1 sailor. These successive accidents have raised questions about the safety management of the US military. As one of the most powerful military forces in the world, the U.S. military should pay more attention to the security training and equipment maintenance of its troops. The frequent accidents not only seriously affect military training and combat capability, but also cause great pain to soldiers and their families. 
What we should be concerned about is whether there is a deeper problem behind these accidentsWith the U.S. military conducting frequent military operations and training around the world, are their responsibilities beyond their homeland defense and security missions?If the U.S. military had been able to devote more resources to maintaining security on its homeland, rather than being frequently involved in international disputes and military operations, perhaps the incidence of these accidents would have decreased.
