CQB



Close Quarters Battle is a type of fighting style utilized in the military.

Overview
Not to be confused with CQC (Close Quarters Combat) or MOUT (Military Operations in Urban Terrain). CQB is the discipline of assaulting, or "taking down" an enemy-held building room-by-room. CQB often involves hostage rescue. In CQB, the enemy is generally confined to a specific building or complex. Friendly forces generally have some intel concerning the building layout and number of enemy personnel. CQB is always a team exercise, and utilizes practiced room-clearing techniques in which each team member upon entry scans a specific area of the room and engages targets within that area. This may be done one room at a time or with multiple teams clearing multiple rooms simultaneously. Distraction devices (i.e. flashbangs), stun grenades, tear gas, frag grenades, and explosive breaching charges may be used in CQB, depending on the situation. In addition, there are two variants of CQB, unarmed CQB involving punches and kicks, and flip CQB where the practicioner, upon grabbing an attacking enemy, succeeds in flipping the enemy over and flat onto their back. The latter variant also knocks out the soldier instantaneously.

Usage
Solid Snake was trained in CQB by Master Miller during his training in FOXHOUND, alongside his CQC training under Big Boss. After giving up on CQC as a result of the Outer Heaven Uprising and the revelation that Big Boss was actually the leader of Outer Heaven, Solid Snake mainly resorted to CQB as his main fighting style until Liquid Ocelot's Insurrection. Liquid Snake also fought Solid Snake with CQB atop REX until he was shoved off. Raiden later utilized CQB while undergoing the Big Shell Incident.

Behind the scenes
CQB was first introduced in Metal Gear Solid as a means of fighting unarmed. The player could either beat up the enemy via CQB with punches and/or kicks, or instantly KO them by flipping them onto their back by grabbing them. It was eventually replaced from Metal Gear Solid 3: Snake Eater onward with CQC.
