How far above the elbow can personnel roll their sleeves when authorized?

When personnel are authorized to roll their sleeves, the standard allows for the sleeves to be rolled up not more than 3 inches above the elbow. This regulation is designed to keep the uniform looking neat and professional while allowing some flexibility for varying working conditions. The 3-inch roll provides enough room for movement and comfort without compromising the overall appearance of the uniform or straying from the military's standards for presentation.

While the other options suggest differing measurements, the 3-inch rule represents the established guideline that balances functionality with formality in uniform wear.
