USS Milius (DDG-69) is an Arleigh Burke-classAegisguided missile destroyer of the United States Navy. Her namesake is Commander Paul L. Milius (1928-1968) of U.S. Navy squadron VO-67. His OP-2E aircraft, callsign Sophomore 50, was hit by anti-aircraft fire over Laos on 27 February 1968 and he ordered his crew to bail out. Seven of the nine men aboard were rescued. The remains of the eighth crewmember, ATN2 John Hartzeim, who was wounded in the attack, were identified on 19 February 1999. Although he exited his aircraft, Commander Milius was never recovered. Commander Milius received the Navy Cross in 1968.
The motto of the ship is "Alii Prae Me" (Others before me). As of February 2016, the ship is part of Destroyer Squadron 21.
Marines, also known as a marine corps and naval infantry, are an infantry force that specializes in the support of naval and army operations on land and at sea, as well as the execution of their own operations. In the majority of countries, the marine force is part of the navy, but it can also be under the army like the Troupes de marine (French Marines) and Givati Brigade (Israeli Marines), or form an independent armed service branch like the United States Marine Corps and Royal Marines.
Historically, tasks undertaken by marines have included providing protection from war while at sea, reflecting the pressed nature of the ships' company and the risk of mutiny. Other tasks would include boarding of vessels during combat or capture of prize ships and providing manpower for raiding ashore in support of the naval objectives.
With the industrialization of warfare in the 20th century the scale of landing operations increased; this brought with it an increased likelihood of opposition and a need for co-ordination of various military elements. Marine forces evolved to specialize in the skills and capabilities required for amphibious warfare.
