Cow



Cows are featured as a running gag throughout the Call of Duty series, especially in some of the earlier games in the series with levels that take place in Normandy. This prompted the developers to jokingly put "No cows were harmed in the making of this game" in the credits.

Locations
They are featured extensively in games such as Call of Duty, Call of Duty 2, Call of Duty 2: Big Red One and Call of Duty 3.

Call of Duty 4: Modern Warfare
The cows also make an appearance in Call of Duty 4: Modern Warfare in the levels Safehouse and Heat in the fields near the barn.

Call of Duty: World at War
The cow is also seen in the Call of Duty: World at War mission Their Land, Their Blood when a dead German is laying on one, this is found inside the barn next to a Death Card.

Call of Duty: Modern Warfare 2
In Call Of Duty: Modern Warfare 2, they appear in many multiplayer maps such as Rundown and Wasteland (a remake of 1 and 2's Brecourt, which also featured cows).

Dead Ops Arcade
Cows appear in DOA as animals who walk across the map in single file lines. Anything that touches a cow will get trampled. They can only be killed by explosives. Glowing cows give the player a large amount of treasure when killed.

Giant Cow Easter Egg
An easter egg, known as the "Giant Cow" is, as the name suggests, a giant cow. It is an oversized cow with a large bell seen in Call of Duty: United Offensive, in the level "Crossroads".
