The player, an Army Ranger caught in the Zakhaev International Airport massacre, must fight through several ambushes while trying to get to the extraction point.
There are several waves of FSB troops in this mission, which are triggered at specific points in the level.
Those wielding the Riot Shield can only be defeated with explosives, careful shots to exposed arms or toes, or flanking (which is a dangerous tactic on this mission). It is also possible to melee them through the shield twice to kill them. However, don't overestimate the threat from the Riot Shield officers, the main danger is from the other FSB officers who are fast and have assault rifles.
At the beginning of the level when the second wave of FSB is triggered from the second level, the two elevators beside the staircase are destroyed by explosives. This is likely as the map is shared directly with "No Russian" where Makarov's men toss a grenade in the elevator to eliminate the Zakhaev Airport Security, so this explosive sequence remained programmed in the Special Ops. The multiplayer level Terminal is actually a different layout.
Terminal is the only Special Ops mission that the player starts with a secondary weapon in the primary slot and a primary as a backup weapon.
