No Tolerance Act - Directs the Secretary of Defense (DOD) and the Secretary of the department in which the Coast Guard is operating to establish and maintain a policy to uniformly define and prescribe what constitutes an inappropriate and prohibited relationship, communication, conduct, or contact, including when such an action is consensual, between: (1) a member of the Armed Forces (member) who is superior in rank to, exercises control over, or supervises a person during entry-level process or training; and (2) a prospective member or member undergoing such processing and training. Makes violators subject to prosecution under the Uniform Code of Military Justice (UCMJ).
