In multiplayer, the player obtains a pair of binoculars for scouting when the rank of Sergeant is reached. When the rank Platoon Sergeant is reached, the player can call in artillery strikes by using the binoculars and pressing the primary fire button. An artillery strike consists of 15 artillery shells that fall within a 850in radius every 2 seconds, making the whole artillery strike last for a duration of 30 seconds. Each artillery shell deals 2000 damage directly and causes explosive damage of 300-10 in a 500in radius, making it the largest explosion in the game. A single artillery strike will lay waste to bunkers, vehicles, and infantry alike, making it the single most devastating attack in the game.
At close range, binoculars can be used as a melee weapon, clubbing them in a downwards motion. It is important to note that this attack does far less damage than melee with any other weapon and will require several hits on an enemy to kill them. If the player makes a melee kill with the binoculars, a binocular icon appears in the kill feed instead of the normal melee icon.
Call of Duty: Finest Hour, Call of Duty 2 and Call of Duty 2: Big Red OneEdit
In Call of Duty: Finest Hour, Call of Duty 2 and Call of Duty 2: Big Red One', the binoculars are used mainly for observation purposes, occasionally for calling in artillery or air strikes. In some levels, the lenses can get foggy after extended use without leaving the view. Binoculars in third person look like aiming down sights.
In Call of Duty 3, binoculars are only used in certain missions to direct tank and artillery fire. If the player chooses to be the "Scout" class in multiplayer, they are given a pair of binoculars and a sniper rifle. Over time, the artillery indicator at the bottom right hand corner fills up with white. When it is full, an artillery strike can be called in. The artillery can also hurt teammates, but it is devastating on infantry.
In Call of Duty 4 the binoculars are used by John Price and MacMillan in the "One Shot, One Kill" intro. The binoculars were usable by player on early stages, as there is string in cut Training mission, binoculars icon in Deep Impactteaser and fake Vladimir Putin review, "Expose Enemy" perk icon, and the string about binoculars in weapons localization strings. Also, Kamarov uses binoculars in "Blackout" to watch his troops invade a village from a power station.
The binoculars are briefly seen in the level "Eye of the Storm", where an enemy Russian is using it to spot targets for a sniper on the rooftops before being silently taken out from behind by Captain Price and Kamarov.
The Binoculars are used several times in the campaign. In "Celerium", they are used to observe a Cordis Die facility. In "Old Wounds", they are used to watch an advancing tank. In "Time and Fate", they are used to spy on Raul Menendez in his estate. In "Dispatch", they are used by a JSOC operative to watch Tian Zhao's incoming VTOL. The pair of binoculars itself reuses the skin from the previous game.
