A February 2005 memorandum from the Aberdeen Proving Ground, a United States Army weapons test site, discouraged shocking soldiers with TASERs in training, contrary to TASER International's recommendations. The Army's occupational health sciences director affirmed the TASER's effectiveness, but warned that "Seizures and ventricular fibrillation can be induced by the electric current." and that "the practice of using these weapons on U.S. Army military and civilian forces in training is not recommended, given the potential risks."
