How do i become an RN or LVN in the US Army?

The Army will pay for school, you choose the school. You can go for a degree in accounting or whatever. Army will come first. not your school. The Army's tuition assistance pays for the school. In active duty I know there is a program for PA, not sure about RN. Unless something has changed with in the last year you do not have to be in the Army 3 years to start taking advantage of tuition assistance. When I was a squad leader one of the first thing I did with a new Soldier was get them enrolled into college.
