Emplacement

An emplacement is a weapon (often crew-served) stationed at a fixed point on the map. Emplacements are often positioned near control points and choke points to provide any nearby defender with a suitable weapon against possible assailants.

In most Battlefield games, there are three types of emplacements, meant for use against infantry, armor, and aircraft.

In Battlefield 2142
BF2142 does not feature an anti-infantry replacement, though both remaining alternatives can be used to good effect. Both Rorsch emplacements feature an armored canopy that can withstand a single tank round from the front, and most other weapons from the rear and above.
 * Anti-armor:The Rorsch Mk-S8 railgun more closely resembles a sniper rifle with its very high accuracy and precision, and high rate of fire compared to other anti-vehicle weapons. Secondary fire activates a high-precision mode that slows movement, but causes all shots to hit directly on the crosshair (actually slightly right due to barrel placement).
 * Anti-aircraft:The Rorsch Kz-27 flak cannon features dual barrels and a guided EMP missile system (similar to the Battlewalkers). The fragmenting shells will detonate near aircraft, inflicting splash damage.
 * Strike at Karkand 2142—Anti-infantry: The future version of the classic BF2 map features machine gun emplacements like the original. The gun models are the same as those used by the Support class. As part of the BF2142 v1.50 patch, this is the only map to feature anti-infantry emplacements.
