Laser designation is the use of sighting and ranging device for precision warfare. Guided ("smart") weaponry attuned to the designator can track the designated target, minimizing collateral damage and maximizing weapon efficiency.
Laser designation was an intended feature in Battlefield 2. However, along with its related gadget, the feature was cut. The player would use the LP7 laser designator to guide missiles to their target.
Laser designation is a feature in Battlefield 3 that is only done on vehicles through a variety of gadgets. Once targeted, a red dot and trapezoid will appear on the intended target, visible by the spotter and any weapon carriers, as well as aircraft and tanks.
The spotter earns 10 points for designating a target, regardless of whether it is attacked or not. The spotter also earns points whenever a designated target is struck with guided weaponry.
Certain gadgets and specializations provide target designation:
Similar to glint from high-powered rifle scopes, lasers can be spotted from a distance as a red glint.
Various weapons can be guided by laser designation:
- FGM-148 Javelin (Engineer)
- Guided Missile (Air vehicles, Artillery, IFVs)
- Guided Shell (MBT, Tank Destroyers)
Laser designation returns in Battlefield 4 as a means of guiding weaponry onto vehicle targets.
As of the beta, all Engineer launchers can make use of laser designation. Vehicle-mounted options specifically for designation have not yet been seen, but the Laser Guided missiles available on some vehicles combine both designation and guided weaponry in one slot.
