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.
1 If you lose a toenail, it might take a year and a half to grow back! 2  Fingernails grow faster on your larger fingers and on your right hand if you're right-handed, and your left hand if you're left-handed.  Fingernails also grow faster during the day and in the summer.
