This bill seeks to prohibit the Department of Defense from utilizing live animals in its live fire trauma training exercises. It explicitly mandates that the Secretary of Defense ensure no live animals , including dogs, cats, nonhuman primates, and marine mammals, are used for these specific training purposes. The legislation further requires that, to the extent deemed necessary by the Secretary, these live animals be replaced with alternative training methods. These approved alternatives include advanced simulators , mannequins, cadavers, or human actors, ensuring continued effective training without animal involvement.
