(AP Photo\/Matt Rourke)\n Army retained the CIC Trophy \u2014 awarded to the team with the best record in games among the three service academies \u2014 after winning it for the first time in 22 years last season and snuffed a late Navy (3-10) rally to retain possession of the patriotic prizeWith Navy down 10-7, quarterback Zach Abey lost a fumble on fourth-and-12 deep in its own territory. Hopkins would score on a 1-yard run to make it 17-7 and give Army the cushion it needed to win in front of 66,729 fans at Lincoln Financial Field.Army hopped and waved hands in celebration during a replay timeout and got the cadets in the stands to bounce along. They had good reason to celebrate: Army has regained its grip in a series that had gotten out of hand. Navy had a series-best 14-game winning streak from 2002-2015 and leads the series leads 60-52-7.Trump sat on the Army side in the first half and crossed the field to the Navy side at halftime. Trump officiated the coin toss and was introduced by public address announcer Dan Baker to a cheering crowd. Navy called "tails," and that's what it was when Trump's flipped coin landed on the turf. Navy elected to kick off.That was a mistake.\n Navy's Zach Abey leaps for a high snap during the first half of an NCAA college football game against Army, Saturday, Dec. 8, 2018, in Philadelphia. (AP Photo\/Matt Slocum)\n Kell Walker ran 51 yards to the 10 on the fourth play from scrimmage and Hopkins dashed in for the TD on the next play for a 7-0 lead.In a series steeped in tradition \u2014 the "March On" and drumline battles, among them \u2014 perhaps none is more ingrained than the running game. Last year's game had a combined three pass attempts and quarterbacks for each team are usually the leading rushers. But Army and Navy passed on the rush and tried to throw, with mixed results. Army safety Jaylon McClinton had an interception in the first half. Army also dropped a key third-down pass that led to John Abercrombie's missed 33-yard field goal in the second quarter.Abercrombie rebounded to kick a 33-yarder in the third for a 10-0 lead.Last season's game was an instant classic and was decided by a field goal: Bennett Moehring narrowly missed a 48-yarder in the snow on the final play and Army held off Navy 14-13.Moehring made the extra point on Lewis' score and he kicked a 45-yard field goal with 29 seconds left. Malcolm Perry's 43-yard run to the 5 set up Garret Lewis' 1-yard rushing TD with 7:10 left in the game that pulled Navy to 10-7.There were reminders all around the Linc, home of the Super Bowl champion Eagles, that this was no ordinary game. The Navy "Leap Frogs" parachute team earned a roar from the crowd with each safe landing on the field. Bill the Goat, Navy's mascot, was safely leashed and secured from a possible abduction attempt from overzealous cadets. And each side safely returned "captives" in the Prisoner Exchange \u2014 when seven midshipmen and seven cadets swap service academies for a semester. The Army prisoners spelled out "3-PEAT on the back of their uniforms.
