The Red Dot Sight is an attachment featured in the singleplayer of Battlefield: Bad Company 2 as well as a primary Specialization in the game's multiplayer. It replaces a primary weapon's standard iron sights with a precision non-magnifying reflex sight with the aim point of a red dot.
— In-game description
The MG36 mounts a reflex sight with a red dot by default (and therefore will not change when a red dot sight is attached).
Being most effective at short-to-medium range due of its low ADS (Aim Down Sight) time and lack of zoom, it is most useful on guns which have obstructive iron sights, as it allows for a clearer sight picture and easier target acquisition.
The sight is invaluable in dark areas, where iron sights may be difficult to see. The sight specialization is partnered with the weapon, not the player. If a player were to acquire a new weapon in the field the scavenged weapon will not have a sight unless its original owner equipped it.
Likewise, if a player were to acquire a new weapon with a scope without equipping it at spawn, the player will have the benefit of both the scope and keeping their original choice of specializations.
