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.
If you are having an accident which causes the big toe nail to come off instantly, you might want to be cautious about some things to prevent more severe infection. A separated nail from the nail bed will not reattach. Instead, a new nail will grow back within a quite long time. A big toe nail, for instance, requires up to 12 months to regrow completely. This new nail might also be in a different shape from the separated one, as this nail grows after the nail bed is injured.
