U.S. Marine Corps wants three types of amphib vehicles, one with 30mm cannon

The U.S. Marine Corps is looking to plus up the firepower aboard its new amphibious combat vehicle with a 30mm cannon, Todd South reports on The Marine Times. Officials with Marine Corps Systems Command posted a request for information on the government website FedBizOpps on 28 January. The ACV will replace the aging assault amphibious vehicle, which entered service in the early 1970s.
