Marines must request paternity leave within 25 days after the birth of the baby. If deployed, the commander can approve paternity leave within 90 days of deployment and can authorize it outside that time period for extraordinary circumstances.
An injury to a nail may result in the loss of the nail. As long as the nail bed itself wasn't damaged, a lost nail should eventually grow back. Healthy fingernails grow at a rate of about 0.10mm per day, but toenails are slower, growing at only about one half to one third of a fingernail's rate.
Fingernails may take 6 months to grow back, and toenails may take 12 to 18 months to grow back. Surgical nail removal is usually performed only when a large portion of the nail is diseased and damaged or if your nails are very painful. In some cases, only the diseased portion is removed, not the entire nail.
