If your over 26 you should be good at least for the start of it.
Redirecting...
The Selective Service System, otherwise known as the draft or conscription, requires almost all male U.S. citizens and immigrants,
ages 18 through 25, to register with the government.
According to the selective service,
if a draft were held today, those who are 20 years old -- or turning 20 during the year in which the numbers are drawn -- would be the first to go. Beginning Jan. 1 of the year an eligible male turns 21, he would drop into the second priority category, and men born the following year would move into the priority group one. Each succeeding year, a draft eligible man drops into the next lower priority group until he has reached his 26th birthday, at which time he is over the age of liability for the draft.
