The main purpose of this legislation is to prohibit the use of live animals in trauma training exercises conducted by the Department of Defense. The objective is to protect animals from being harmed during military training, promoting a more humane approach to preparing military personnel for emergency medical situations. Key provisions of the legislation include a clear ban on the use of live animals, such as dogs, cats, nonhuman primates, and marine mammals, in any live fire trauma training. The Secretary of Defense is tasked with ensuring this prohibition is enforced.
