The Navy is loosening the standards of the infamous tape test in its physical examination. Meanwhile, the Marines remain saddled with an unfair physical exam even though it is technically a part of the U.S. Department of the Navy.

For a sailor or Marine to successfully ‘tape-in,’ the serviceman’s neck and waist measurements must fall between certain acceptable thresholds. This test is meant to measure the neck to waist ratio of a military member and estimate body fat. Failing the tape test can cause a serviceman to fail their entire physical examination and possibly get booted from service.

The test is notorious for being unreliable and inaccurate. Instead of measuring weight or fat, the test measures size. This means that anyone with enough muscle tone can fail to tape-in, even if they don’t have an ounce of fat on their bodies. In 2013, The Military Times investigated the issue and found that the tape test contained a margin of error that ranged between 12 to 66 percent.

Even if accuracy wasn’t an issue, the test’s rigid standards have driven servicemen to starve themselves, get liposuction and lose muscle mass in order to obtain the right measurements.

The Navy will adopt the Air Force’s tape test by next January, which only measures the waist.
