Can my friend just walk away from the army?

In most cases, yes, your friend can walk away from the army. Most countries have set terms for when a soldier can terminate their contract, and usually it will be at some point before their contract is due to expire. It may be necessary for your friend to pay a fine or otherwise fulfill their commitments before being officially discharged, so it is worth speaking to their chain of command and the military authorities before doing anything.  If your friend is based in the US, Army Regulation 635-200 confirms that soldiers can leave the military at any time before their contract end date, provided they have notified their superior officer at least 180 days before their desired release date.
