Four Lions is a 2010 British satirical black comedy directed by Chris Morris about five would-be Jihadist suicide bombers in London and their bumbling attempts to carry out a terrorist attack.
The following weapons can be seen in the movie Four Lions:
Rifles
Fake AK-47
One of the Jihadists, Waj (Kayvan Novak), uses a fake AK-47 in one of the videos. As a miniature dummy, it is very unconvincing.
AKMS
In a Jihadi training camp in Pakistan, Waj (Kayvan Novak) acquires an authentic AKMS rifle and fires it in one of the videos, naturally irritating camp leader Khalid (Willliam El-Gardi) due to the presence of American drones in the area.
Heckler & Koch G3SG/1
A British Police Sniper uses a Heckler & Koch G3SG/1 to shoot a "Wookie" mistaken for one of the terrorists. This leads to a hilarious exchange about whether a wookie or a honey monster is a bear.
British Counter-Terrorist forces are armed with Heckler & Koch MP5A3 submachine guns mounted with Surefire tactical lights and ACOG sights.
Sidearms
Glock 17
One of the British officers briefly carries a Glock 17.
Launchers
M136 AT4
A stash of M136 AT4 missile launchers are seen at the training camp. Omar (Riz Ahmed) tries to take down an enemy drone with one. However, he holds it the wrong way around and it backfires (literally), and ends up killing Osama Bin Laden.
