It is the Law!
Virtually all male U.S. citizens, regardless of where they live, and male immigrants, whether documented or undocumented, residing in the United States, who are 18 through 25, are required to register with Selective Service.
The law says men must register with Selective Service within 30 days of their 18th birthday. That means men are required to register with Selective Service sometime during the 30 days before their 18th birthday, their 18th birthday, and the following 29 days after their 18th birthday – that is a 60-day registration period.
Men who do not register with Selective Service within the 60-day window are technically in violation of the law and should register as soon as possible. Late registrations are accepted up to the 26th birthday. However, once a man reaches his 26th birthday and still has not registered with Selective Service, it is too late!
It’s important to know that even though a man is registered, he will not automatically be inducted into the military. Registering with Selective Service does not mean you are joining the military.
In a crisis requiring a draft, men would be called in a sequence determined by random lottery number and year of birth. Then, they would be examined for mental, physical, and moral fitness by the military before being deferred or exempted from military service or inducted into the Armed Forces.

I not only registered but joined the U.S.M.C. So I am both militia and military and thats my defense to as why I need my AR.
Whenever a friend or family asks why I own an AR, My reply is always because "That it is what the marine Corps taught me to maintain, operate and shoot safely. When required."
