So a couple years pass, he gets promoted to E4, and attends Ranger school, and completes it. At that point, he'd be awarded a V Special Qualification Identifier for Ranger Parachutist (i.e., Airborne Ranger), so his MOS would read 11B1V.
How to Manually Check Your Heart Rate. A normal resting heart rate for most adults is between 60 and 100 beats per minute. Conditioned athletes typically have resting heart rates closer to 60 beats per minute. If your resting heart rate is greater than 100 beats per minute -- or less than 60 and you are not an athlete -- visit your doctor, who can diagnose any underlying condition you might have.
Now, practice finding your pulse point and calculating your heart rate: Place one or two fingertips (not a thumb) on the opposite wrist, just below the base of your thumb. Count the number of heartbeats you feel in 10 seconds. Multiply that number by six to get your heart rate per minute.
