so look at the plan for pulling out of the last area of operations we are currently in here:

if he's going to graduate in 2017, i seriously doubt, barring a new major conflict beginning elsewhere in the world, that he will deploy. in the information meeting the admissions officer from west point held in Oct 2011 for the class of 2016, asked who is thinking they will deploy. i was the only person who raised his hand, cause i'm currently enlisted. and he agreed with me. by 2016, we are supposed to be out of ahganistan, and are on track to do it.
you also have to figure into the timeline post graduation, the BOLC course, which varies branch to branch, if he decides to try for a masters degree, if he is in a non-combat branch and what his duty station is. Korea isnt a combat tour, but he is overseas for a minimum of 12 months. germany isnt a combat tour, but he is over seas for 2 years.
It also has to take into account what type of unit he is in. there are combat brigades, and other brigades. for the most part, combat brigades will do the majority of the deployments. i'm not saying that other types of brigades dont, but a combat brigade is for the most part self sufficient.
and if he is joining the army. he, if his nation calls upon him to, will deploy to a combat zone. its a fact of the life. not to get on a soap box, but if you're going to join the military in ANY aspect, be ready for that, and make your peace with that.
