Jody Simmons rushed for 96 yards, 37 coming on a touchdown run, and teammates Mike Brown and Marty Louthan scored on runs of one and six yards yesterday as the Falcons won, 27-9, at West Point.

Air Force, which earlier beat Navy, also won its first outright Commander-in-Chief trophy. The award, first presented in 1972, is given to the team with the best record against the two other major service academies. The Falcons tied their series with the Cadets at 8-8-1.

After the teams had exchanged punts, Air Force (6-4) marched off to a 17-7 halftime lead. Dennis Moore returned an Army punt 27 yards to his 45 and, five plays later, Simmons took a pitchout 37 yards down the right sideline. Army (4-5) tied with an 11-play, 80-yard drive ending in Gerald Walker's six-yard run, but the Falcons countered with a 15-play scoring drive from their 20, quarterback Louthan gaining 31 yards on four keepers and Brown scoring from the one.

Air Force next got to Army's 10, but two penalties put the ball back at the 27 and Sean Pavlich kicked a 37-yard field goal with 7:04 left in the half.

In the third quarter, Army twice got inside the Air Force 20, but Craig Stopa, 12 of 15 on field goal attempts entering the game, missed from 34 and 36 yards.
