Okay, so I have a player than wants to play a PC that is their late 40's early 50's. He was part of the first wave of stormtrooper corp recruits. Something happens that gets him court-martialed and imprisoned (he hasn't worked that out). The prison is completely droid operated and the prisoners are subjected to COMPNOR's "rehabilitation" holovids continually playing around them.

Then one day, after the facility's existence slipped through some Imperial Bureaucracy's notice, the facility's systems shut down and all the cells open up. The PC manages to get off-planet and re-enter's society but the decade of isolation and COMPNOR leaves him with some serious "issues."

Mechanically, he's thinking that he started out with a strong allegiance to the Empire, he grew up seeing the Jedi destroying the galaxy with their wars and has been thoroughly indoctrinated. When he was imprisoned, it was unjust as he believes himself innocent. This causes the rift in his beliefs and he is devastated that the empire he loves would do this to him, of all people.

So essentially, he wants to treat his indoctrination into Imperial Duty and his feelings of betrayal, plus years of isolation as an obligation similar to what I would think severe PTSD would likely be like.

How would you guys assigned the obligation mechanically?

Call it Rehabilitation and follow the rules as usual. If his Obligation gets rolled, he suffers the -2 to Strain Threshold and every time he has to do something that goes against... Imperialness... he has to make a Hard Discipline check. If he fails the check, your player can choose to not do whatever or do whatever with two or three Challenge dice tossed in.

So I have a player who's character is a former Clone Trooper pilot, been fighting since the Batitle of Geonosis.

Long story short, his vessel was heading to Kamino at the end of the war, crashed in the middle of Tusken Raider territory. He survived alone for 20 years with the remaining supplies from the ship. He already had reason to distrust jedi before and with all he suffered, he has flashbacks and trouble maintaining control around force users. His inhibitor chip was damaged in the crash.

For his obligation, betrayal was chosen. He distrusts both Jedi and the Republic, now the Empire. We worked out the effects to being that he has an automatic upgrade to everything he does when around force users (our group always has at least one) and he will have flashbacks, leading him to search for the missing pieces of his memory.
