Second Battle of Arcadia
During the second Covenant Empire invasion of the colony planet Arcadia, Anthony-095 and his squadron of Spartan IIs were sent to help with the evacuation of several civilian cities. During the firefight, all of Anthony-095s squad mates was killed by Covenant forces. Tactical Intelligence proves forces involved were Elite Zealots, as several Spartans were killed by Energy Sword burns and plasma radiation. Anthony-095 was able to help the last of the civilian transports escape, and was awarded the Silver Star by Fleet Admiral Lord Hood.
Battle of Reach
Years later, the Covenant armada invaded Reach space. Anthony-095 was tasked with destroying the Covenant supercarrier "Long Night of Solace", but was later reassigned to protecting the Office of Naval Intelligence Sword Base. When the full force of the Covenant Empire hit Reach, Anthony-095, along with Gray, Blue, Red, Echo, Zulu, IPT, and NOBLE teams, were assigned to defense of valuable UNSC assets and civilian protection. Before the 'glassing' of Reach, Anthony-095 was able to escort Captain Jacob Keyes to the UNSC cruiser "Pillar of Autumn". Later, he united with SIII-266 Jun, and assisted in escorting Doctor Catherine Halsey to the Office of Naval Intelligence Castle Base, before escaping the planet in a abandoned Covenant Seraph, and flying to a nearby moonbase. There, he was refitted with an space-based Longsword and escaped to Earth, before the moonbase was obliterated by a Covenant corvette.
Battle of Earth
Before long, the Covenant Empire had invaded the inner colonies of the UNSC and closed in on Earth in force. As Lord Hood pressed his attack on the incoming Covenant fleet, Anthony-095 was sent to defend the nearby space-based stations from Covenant control. All stations in Sol space were eventually destroyed by the incoming Covenant onslaught, until they reached Earth. Anthony-095, alone, was deployed to New Mombasa while John-117 attacked the Covenant carrier controlled by the Prophet of Regret. When the Covenant gained complete control over New Mombasa, Anthony-095 worked in a joint-operation with John-117 and the Elite Arbiter to destroy all Covenant Anti-Air Turrets in the immediate area, allowing Lord Hood's fleet to launch a final strike against the enemy armada. This attack failed, and the Covenant leader, the Prophet of Truth, escaped to the Forerunner Installation 00, or The Ark. When the parasitic Flood landed at New Mombasa, all UNSC forces were ordered to scatter and avoid the Elite glassing. Anthony-095 was not seen after the event.
