Will there be a military draft for the Iran war?
Extremely unlikely — under 5% probability. The US has 1.3M active duty and 800K reserve forces, more than sufficient for current operations. Congress would need to pass new legislation to reinstate the draft.
Who is eligible for the military draft?
All male US citizens and immigrants aged 18-25 must register with Selective Service. If a draft were activated, men 20-25 would be called first, starting with 20-year-olds.
Is Selective Service registration the same as being drafted?
No. Registration is a legal requirement for all men 18-25, but it does not mean you will be drafted. A draft requires separate congressional authorization, which has not happened since 1973.
