M4A1

The M4A1 is used by all friendly forces throughout the Forgotten series. It's used by American special forces, British SAS commandos, Russian Loyalists, and Serbian Loyalists. 
==Appearances==
The M4A1 is seen in all three Forgotten books, used by Americans in Forgotten: Apocalypse, Global Tyranny Peacekeepers and Global Community officers in Forgotten: The Mark. Finally, it's used by the Unity Army, SAS, Serbian Loyalists, Russian Loyalists, Delta Force, Rangers, and Marines in Forgotten: Armageddon. 
==Trivia==
*At first, the Serbian Loyalists were supposed to use the weapon first, but this was changed to all friendly forces.
*The M4A1 used by everyone is actually modeled after the one in Modern Warfare 3.
*Originally, the M4A1 was supposed to be used by the British SAS more than Delta Force, but this was reversed.
