The OPAT App is designed to educate ALL Army Recruits and Soldiers reclassifying from the Combat Support and Combat Service Support Military Occupational Specialties (MOS) who desire to enter into a Combat MOS. A physical assessment of four test events; the Standing Long Jump, the Seated Power Throw, the Strength Deadlift, and the Interval Aerobic Run, the OPAT will measure each recruit and Soldiers' physical aptitude against validated physical demands and tasks in each MOS to help ensure they are being placed in the right job positions.

The app was created in partnership between the United States Center for Initial Military Training and the TRADOC Program Office Mobile Team.
