Light automatic weapons are recommended for this map. Because of the prevalence of close quarters combat,assault rifles and submachine guns are preferable. Shotguns, especially the AA-12 for its automatic fire, are also highly effective at sweeping alleyways and clearing rooms. A class with Marathon and/or Lightweight can be very effective in getting around the map quickly, and for surprising enemies.
A good tip for snipers is to not always seek the high ground, but to look for wide open areas where a runner is an easy target, and make sure that the location one is sniping from is either hard to get to or has only one entrance to prevent embarrassing knife deaths. A neat little spot is on the roof next to the building with the stone cover, as the roof is a hard spot to target without one noticing. The only problem with this spot is getting killed from behind, but that is not much of a problem because the TF141 spawn point is on the other side, giving the sniper an advantage when they run outside.
This map features many effective places to place claymores, especially in tight alleyways and corners found in the center of the map. Claymores can be a very effective way to defend flags B and C, and to a lesser extent A, in Domination gametypes. Also in domination, it can be a good tactic to place a C4 pack on B, (when the players team has it captured) and, as it is a high-traffic area, as soon as the player hears that they are losing B, they can detonate the C4 gaining at least 1 kill.
In Domination, a good place to defend A, (Task Force 141 spawn), is behind the flag, players can see a small trench with a small bridge of boards in the middle. Players can sit in here and have an almost complete view of the entrances. When a few people start to get killed, enemies will start taking counter-measures against the player, such as throwing grenades into the trench, or flanking the player. Because of this the player needs to be aware of his surroundings at all times while in the trench, if fighting against a player in the trench, players should make sure take a good look around the A flag, as there may be a player, or a group, waiting to take them out when they get near, or start capturing A. Also with Lightweight and Marathon, if the player decides to attack while on the TF141, a player can run from point A to point C before the enemy captures it and kill everyone with a Semtex. Also, it is possible to capture B from inside the ice cream shop nearby.
If using a Harrier Airstrike, a good place to call it in is the large courtyard (the large area between B and C), it can easily gun people down due to a lack of cover for players, but with buildings adding to it's protection making it hard to shoot down.
First Blood kills can be easily done when spawning as part of the Militia by throwing a grenade up the south road, aiming so it lands near the car at the top.
There is an easy, little-known way to enter the barbershop which can be extremely useful in modes such as Headquarters Pro. If a player climbs onto the roof of the Grifter's Green House (The two-tiered house across from the barber's), they have a clear view of the lone window in the barbershop that faces west. If the player runs toward the window while on the roof of the Green House, they can jump into the window and then into the shop itself. If the player mistimes it and doesn't quite make it inside the window, they will still usually land on the small ledge beneath it, where they can then pull themselves up. If there is an enemy looking out the window at the time, one can eliminate them either by shooting them or using equipment. This is perfect for matches where many players camp inside the barber's, covering the two sets of stairs.
