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.
Try measuring your radial pulse, which is on your wrist artery, just below your thumb. To measure your heart rate, gently press the tips of your index and middle fingers over the blood vessels on your wrist. Make sure not to use your thumb, because it has its own pulse. Count the beats you feel for a full minute. You can also count for 30 seconds and multiply the count by two, or count for 10 seconds and multiply by six. Alternatively, you can use a heart rate monitor, which determines your heart rate automatically.
