Mission 4: Diwaniya, Iraq
The mission takes a small departure from its conventional dark and gloomy spy business and places the player in someone else's shoes from 20 years prior. You play as Victor Coste. Sam is here, but he's been taken prisoner.
Find and Rescue your squad leader.
The weapon Victor picks up has a built-in scope and is really handy for scouting ahead. Start moving down the disheveled highway, taking out the enemies along the way. This is no sneak job at the moment, but don't forget to take cover from fire. There are no Executes or anything of the sort. Eventually, Victor closes in on the Iraqian base and spots many soldiers hanging around outside. The huge oil rig parked out front is the perfect way to dispatch a couple at once.
The Iraqians love to carry Frags around with them and won't be afraid to chuck some in Victor's direction to flush him out. Follow the distance marker to another segment of the base, where the game instructs you to search the buildings. The dilapidated building to the left features a couple of chatty soldiers and an explosive barrel. One more soldier is stationed on the roof directly above as well as to the left of the building. Of course, many more are strewn throughout the area. Quickly dispatch this initial bunch and welcome the wave of alarmed soldiers, coming mainly from the right and further north.
Take note of the red-colored barrels along the way, as these will come in handy at a later point. It appears that they've got Sam holed up in an abandoned school building. Weave through the multitudes of classrooms to another building and find Sam being forcibly questioned. Run in with guns blazing to save Sam, but there's no time for a collective sigh of relief just yet. Reinforcements storm to the scene in full force, and the duo must hold their ground before help arrives. On Realism, you never want to stay aggressive for too long here. Spy the red barrels spread around outside and aim for them individually to annihilate a good amount of the assailants. Eventually, help will come and stomp out the resistance here. Cue end flashback mission.
