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.
Most people can see the faint bluish line of their radial artery; place your fingertips here. Count the beats for 1 minute. Or, if you have a short attention span, count for 30 seconds and multiply by 2. During your workout, take your pulse about every 15 minutes and be sure to concentrate. You may want to slow down or even stop while you take your pulse.
