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.
Do not take your heart rate after exercising, as it is likely to be higher from the exertion. Sit upright, expose your left inner wrist and place your index finger and middle finger on the inner wrist near the top edge of your arm, near the base of your thumb. Notice you will feel a throbbing pulse under your fingers. If you don't, move your fingers down or up slightly to locate your pulse. Avoid using your thumb to take your pulse as the thumb will often has its own pulse, which will make it difficult to record your actual heart rate pulse. Keep your fingers on your inner wrist and count the number of beats for 6 seconds.
