In the US Army, there is no compulsory military service - it's an all volunteer military. If someone chooses to enlist, they commit themselves to an eight year obligation, with a minimum of two years served on active duty. If they serve less than eight years on active duty, in a reserve component, or a combination of the two, then they are placed into the Individual Ready Reserve, where they may be subject to recall until the eight year MSO period has passed.
According to the CIA World Factbook, there are approximately 12,000,000 men age 16-49 that are fit for military service in the UK.

No, military pay is based on rank and years of service, not gender. Men and women in the military receive equal pay for equal work and are subject to the same pay scales and regulations.
The Vietnam War had 16 million men that avoided US military service (dodged the draft).
Like all military personnel in the US, they can retire from military service after there first enlistment is over. The standard enlistment is 4 years, but sometimes the first one can be 6 years depending on the branch/career chosen. For the Marines it's generally 4 years. Military Service men and women can re-enlist and if they stay in the Military for 20 years earn a full government pension.
All men
The law for compulsory military service for white boys and men in the United States, known as the Selective Service Act, was first passed on May 18, 1917, during World War I. This act allowed the federal government to draft men into military service, which was later expanded and revised in subsequent years, notably during World War II and the Vietnam War. Ultimately, the draft was suspended in 1973, transitioning the U.S. military to an all-volunteer force.
