(Tribune News Service) — The Marine Corps' top leaders will speak before a Congressional committee on Monday, May 3, addressing lawmakers' concern about a "lack of safety" and an uptick in training accidents. The appearance was prompted by a recently released investigation into the most deadly accident the Corps has had training with the amphibious assault vehicles that have been in use since the 1970s. With the number of military training accidents and fatalities outpacing combat deaths in recent years, lawmakers have been holding hearings on the apparent trend since 2019. California representatives John Garamendi, D- Walnut Grove, and Rep. Jackie Speier, D- Hillsborough, who both sit on the House Armed Services Committee, asked for Monday's review of the details in the latest AAV accident.
