Josh McNary isn’t your run-of-the-mill street free agent acquisition by the Indianapolis Colts.

He’s a lieutenant in the Army. His two-year active service commitment, which kept him from being selected in the 2011 NFL draft, ends May 21. At that time, he’s eligible to be formally released from the military and join the Colts.

He hasn’t played since Dec. 30, 2010, when the defensive end’s 55-yard touchdown return of a fumble sparked the Black Knights’ 16-14 win over Southern Methodist in the Armed Forces Bowl in Dallas.

McNary, Army’s career sacks leader, talked glowingly of his four-year stint at West Point and the subsequent two years of active duty during a conference call Thursday.

“I don’t think any other job compares to Army lieutenant with the responsibility (and) how much it demands of a kid so young, straight out of college,” the 6-foot, 251-pounder said.

The experience began with an assignment as a graduate assistant at West Point, primarily working in the strength and conditioning department. Since October, he’s been stationed at Fort Hood in Killeen, Texas, in a leadership position with an artillery unit.

In late May or early June, McNary hopes he’s able to join the Colts’ offseason workouts and resuscitate his football career as a linebacker.
