An animal-rights group wants the military to stop using animals in some of its training.
People for the Ethical Treatment of Animals want Defense Secretary Robert Gates to replace the animals with other methods such as human simulators.
In its letter to Gates, PETA says the military inflicts gunshot, burn and chemical wounds on monkeys, pigs and goats for training. It calls the exercises cruel and a disservice to troops.
This month, the group failed in an effort to prevent the Army from shooting live pigs and treating their wounds in a medical trauma exercise in Hawaii.
The Army says the training teaches soldiers how to manage critically injured patients on the battlefield when there are no medics, doctors or facilities nearby.
