There used to be the option to serve two years of Active Duty (one of my roommates while I was in did a two year enlistment), although I believe that's no longer an option. Three, four, and six year contracts are available, and each reenlistment is typically for four more years, until you get to a point where you have an 'indefinite' enlistment (meaning you'll be eligible for retirement).
Retirement is usually 20 years... it may be more, dependent on what rank you achieve, your position, etc, or it may be less, for instances where the military is being reduced in size, and some senior officers and NCOs are offered early retirement in order to achieve this.
When you enlist in the Army, you have an eight year Mandatory Service Obligation. You may enlist on a four year contract, but, after your ETS date, you will be placed into the Individual Ready Reserve (unless you reenlist, go into a different branch of service, or join a reserve component, such as the Army Reserve or National Guard), during which time, you may be subject to be called back into service. You are not required to attend drill events or anything of that sort while you are on IRR, however.
That depends on the country you are talking about. In the US army, training - basic and advanced - normally takes up to 52 weeks. Specialist functions of course may take longer. But in Israel, first service takes up to 3 years. Other countries that have conscription have first training periods that vary from 6 months to 2 years.
The Police academy usually only lasts 6-8 months, so its less than a year.
JROTC can be taken throughout the four years of high school, or in some special cases, may start in the senior most years of middle school.
