Major Coats

Major Coats is a British Alliance soldier stationed on Earth under the command of Admiral Anderson. He spent three days inside the Big Ben clock tower sniping at anything that moved. He provides covering fire as Shepard is extracted by the UT-47 Kodiak Drop Shuttle.

Later on he is ordered to coordinate the artillery strikes by Admiral Anderson as Shepard makes his way to the Citadel. He can also be heard on the radio, after Shepard is hit by the Reaper laser, telling all surviving Alliance troops to fall back.

Trivia

 * Coats first appeared inside of Big Ben during the debut "Fall of Earth" trailer for Mass Effect 3 and appeared again in the full "Take Earth Back" trailer.
 * Upon careful examination, the M-29 Incisor sniper rifle appears as the firearm that Coats uses during his hold out inside of Big Ben in the the debut trailer for Mass Effect 3. The weapon appears again in the full "Take Earth Back" trailer, still wielded by Coats.
