I think we're fast approaching the point where skills are getting too specialized to train a draftee fast and then get them to the front lines in a timely manner in the kind of war where selective service would actually come into play- I just can't imagine a scenario where the draft is instituted, occurs and actually supplies soldiers to a war zone.
Even in peace time with no draft an unregistered male is exposed to fines/penalties a female isn't. Might as well break all the glass ceilings. In the end, all the "skills" in the world don't equate with "boots on the ground". I'm sure sure boots come in size 5.
From the interwebz:
# CONSEQUENCES FOR NOT REGISTERING
The maximum penalty for failing to register with Selective Service is a $250,000 fine and up to five years in prison. Failure to register will cause ineligibility for a number of federal and state benefits including:
# FEDERAL JOBS
A man must be registered to be eligible for jobs in the Executive Branch of the Federal government and the U.S. Postal Service. This applies only to men born after December 31, 1959.
# STUDENT FINANCIAL AID
Men who are not registered with Selective Service cannot obtain Federal student loans or grants. This includes Pell Grants, College Work Study, Guaranteed Student/Plus Loans, and National Direct Student Loans.
# CITIZENSHIP
The U.S. Immigration and Naturalization Service (INS) makes registration with Selective Service a condition for U.S. citizenship, if the man first arrived in the U.S. before his 26th birthday and was required to register.
# FEDERAL JOB TRAINING
The Workforce Investment Act (formerly JTPA) offers important job-training opportunities. This program is only open to those men who register with Selective Service.
# STATE JOBS, LOANS, AND TRAINING
Most states have added additional penalties for those who fail to register with Selective Service.
