The SIG-Sauer P226 is the preferred sidearm of Red Troop and is used throughout the series. It is frequently seen holstered whenever the team are wearing their counter terrorist gear, but is normally only used for undercover work.
In "Class of 1980" (Episode 3.3) one of the terrorists (San Shella), uses what appears to be an original Beretta 92 for most of the episode. Oddly this particular pistol is fitted with a slide which is thinner at the front than the back and different grip plates, features which do not appear on the majority of Beretta 92s.

"Pre-B" CZ 75
Several of the Chechens in ([[Weapon of choice" carry "Pre-B" CZ 75s.
Several of the terrorists in "Deadlier than the Male" (Episode 3.1) carry Umarex GPDA blank firing pistols that stand in for Browning BDAs. They can be recognised as GPDAs by their slide markings, which are visible in some shots, and the shape of the safety catch.
In Episode 3.2, "Never Go Back", the leader of the Zimbabwean "Fire Brigade" carries a Bruni Automatic 8mm CAL pistol (which is a theatrical blank firing only replica gun). The character may carry a real M1911 in other shots, but in this particular shot, he is aiming it at a child actor, so the blocked barreled replica M1911 is used.

Submachine Guns
Heckler & Koch MP5A3
The standard-issue weapons for the SAS unit Red Troop in the TV show are Heckler & Koch MP5A3 submachine guns, which are always seen with Surefire fore ends and tactical flashlights as well as the SEF-style lower receiver. These weapons are typically used in Red Troop's domestic hostage rescue missions.
The other SAS unit, Blue Troop, also use identical weapons, as do many Metropolitan Police SO19 (now CO19) officers throughout the show.
In Episode 3.2, "Never Go Back", Becca takes a Calico M960A from the stash of weapons and looks it over, though she winds up using a Steyr AUG on the mission.
In "Class of 1980", a number of characters can be seen using what appears to be a Heckler & Koch MP5SFA3, the semi automatic only version of the MP5 used by, among others, the British police.
CAR-15s are used commonly by the SAS in the show, almost always fitted with a Cobray CM203 grenade launcher. The "Stowaway" pistol grip and the areas of black tape covering logos on the lower receiver suggest that this weapon is built from an Olympic Arms rifle, most likely a K3B.
The M16A1 carried by Dempsey (Miles Anderson) in "Never Go Back" (Episode 3.2) changes to a Colt AR-15 Sporter-1 for firing scenes, as noted by its slab sided receiver.
Sergeant Sean Smith (Derek Horne) can briefly be seen carrying what appears to be a Colt Model 723 during a run at the start of "Never Go Back" (Episode 3.2).
A number of Mocked up AK-74s can be seen being used by the African militiamen in "Never Go Back" (Episode 3.2) and by Russian troops in "Weapon of Choice" (Episode 3.4). They appear to be chambered in 7.62x39mm rather than 5.45x39mm, so it is likely that these weapons are AKMs fitted with AK-74 furniture and a muzzle brake.
Henno (Ross Kemp) uses a Heckler & Koch G3A4 as his main weapon in "Never Go Back" (Episode 3.2) fitted with a slimline handguard, PRR pressel switch and an Aimpoint type red dot sight (replaced with a British Kite CWS for night scenes).
Whenever Red Troop requires sniper support, the snipers are typically armed with Accuracy International Arctic Warfare rifles in 7.62x51mm NATO, with the majority of the main characters using one at one point or another. This rifle was used by the British army, under the designation of L118A1.
A police SO19 sniper in "The Class of 1980" (Episode 3.3) can be seen using an unknown Heckler & Koch G3 based sniper rifle. The rifle which it most resembles is an Heckler & Koch G3SG/1 , however it has several differences: the rifle has a conventional trigger pack (lacks the secondary setting trigger), a skeletonised extended butt plate, a larger cheek riser, no iron sights and what appears to be a thicker and longer barrel without a flash hider. Due to the rarity of G3SG/1s, it is more likely that this rifle is a regular G3A3 which has had a number of modifications and after-market parts added. The same rifle can also be seen on the Season 4 page where the same rifle is carried by a US special forces sniper.
A large bore sniper rifle of some variety is inside the weapons crate given to Red Troop in "Never Go Back" (Episode 3.2), but it is never picked up and all that is visible of it is the front of the barrel and muzzle brake.
Dave Louis Decosta Johnson can be seen using an Accuracy International variant in "Weapon of Choice". It doesn't appear to be the Arctic Warfare variant used in the rest of the series, as it lacks the correct flash hider on the end of the barrel, and there are 4 holes visible in the front face of the barrel. It is possible that this is simply an Arctic Warfare with the flash hider removed, but it is not possible the tell as the weapon is heavily camouflage with scrim.
Seen in the first episode of the series, "Killing House", one of the bank robbers had this weapon.
In the Episode Natural Selection, the rogue paratrooper that tried to prevent Candidates from finishing SAS Selection used this to fight and injure other Paratroops.
Red Troop's M16s and CAR-15s are often fitted with what appear to be M203 grenade launchers. However, a close inspection of the receivers reveals that they are actually the look-a-like Cobray CM203 37mm launchers which are often used to substitute for the M203 in many films and TV shows.
