It is possible to save Rocket in the mission since he and other random operatives wielding assault rifles are able to live, they could die just before they arrive at the first LZ. Though it is possible to keep 141 operative Chemo and other operatives wielding SMGs alive.
Often, if the player doesn't kill many of the enemies at the beginning of the level and they go down the street on the right, Rocket will engage in a fierce hand to hand fight with a member of the militia, much like Private Roycewicz in Call of Duty 4: Modern Warfare.
Rocket will always spawn with an assault rifle.
On the back of his vest the player will notice a Canadian flag like on all other Canadian NPC's.
