Sam didn't care about any possible mission that could be assigned to him nor did he give a shit about the war that is going on.
All he cared about was to get Arman back, they might have had their difference, but Arman is someone Sam brought over to this army and he is his subordinates, if he needs to get hit, that would be only in Sam's hands.
Who the fuck are the Regiment commander and his subordinates to plot against Arman.
At this moment the regiment commander also heard about the news Sam leaving to save Arman. He was a bit relieved at this and everyone thought that this is the plan from the start to send Sam to make him trapped in that place.
