The following weapons were used in Season 4 of the television series The Unit:

Pistols

Kimber Warrior

The Kimber Warrior was the sidearm of choice for Jonas Blane throughout Season 4 (and occasionally in earlier seasons), replacing the Custom TLE II.

Another Kimber Warrior used in the most recent season of The Unit - this was Dennis Haysbert's backup weapon in case the first failed (it is customary in Hollywood for each "hero" gun use to have at least one backup on set).

A nice closeup of Jonas' Kimber from Season 4's "Endgame".

Colt M1911A1

The M1911A1 is a frequent weapon seen in the series. Master Sgt. Mack Gerhardt (Max Martini) carries one as his sidearm. An M1911A1 with a suppressor and night vision scope was used by Bob in Season 4's "Dancing Lessons". Another scoped 1911 (likely the same prop weapon) was used by one of the terrorists who tries to kill Jonas when he rescues Molly in "Endgame".

In Season 4's "Dancing Lessons", Bob checks the perimeter of the kidnappers' hideout with the scoped and suppressed M1911A1.

Bob fires his scoped M1911A1.

SIG-Sauer P225

The SIG-Sauer P225 is used by Sgt. Charles Grey (Michael Irby) with a suppressor in Season 4's "The Last Nazi" (S4E14). SSgt. Sam McBride (Wes Chatham) is seen with a P225 in the opening scene of Season 4's "Hero".

SIG-Sauer P225 - 9x19mm

Grey checks the load in his suppressed 225 in Season 4's "The Last Nazi". This is a 225 as evidenced by the single stack magazine.

SIG-Sauer P226

The SIG-Sauer P226 is the sidearm of Sgt. Charles Grey (Michael Irby) and Sgt. Hector Williams (Demore Barnes) throughout the series. Master Sgt. Mack Gerhardt (Max Martini) uses a P226 throughout Season 1 before switching to his M1911A1. P226s are used by a number of Leon Drake's men (including Drake himself) with and without suppressors throughout Season 4.

SIG-Sauer P226 9x19mm

SIG-Sauer P229

The SIG-Sauer P229 is a commonly featured handgun throughout the series. US Army intelligence officer Bridget Sullivan (Nicole Steinwedell) uses a two-tone P229 in the Season 4 premiere "Sacrifice" (S4E01). Mack mentions that she carries a .45, which is incorrect, as the P229 is only chambered in 9mm, .40S&W, and .357 SIG). Bridget's P229 is briefly seen again in "Best Laid Plans". Similar weapons (likely the same prop guns) are used by the female kidnapper in "Dancing Lessons", and the assassin in "The Last Nazi".

SIG-Sauer P230

A suppressed SIG-Sauer P230 was used by one of the Russians who ambushes Bob in Season 4's "Endgame".

SIG-Sauer P230

Glock 17

The Glock 17 is one of the weapons prominently featured throughout the series. Charles Grey (Michael Irby) uses a Glock 17 during the opening scene of "Sacrifice".

A Generation 2 Glock 17 in 9x19mm. This model added finger stepping and cuts to the backstrap of the frame to make it easier to hold than the Generation 1 model.

Glock 19

The Glock 19 is also used by numerous characters throughout Season 4. President-elect Benjamin Castillo (Benito Martinez) is seen with a Glock when he is confronted by the team in Season 4's "Sacrifice". They are used frequently by terrorists in other episodes, including "Switchblade", "Inquisition", and "Dancing Lessons".

A Glock 26 is seen in the gun drawer.

Beretta 92FS

The Beretta 92FS has been seen in the hands of SWAT members, Unit members, and US military CID agents. Sam McBride (Wes Chatham) takes a 92FS from a police officer in "Whiplash" (S4E19).

Beretta 92FS 9x19mm

In Season 4's premiere "Sacrifice" (S4E01), a terrorist disguised as a US National Guardsman tries to pull his Beretta on Bridget.

Makarov PM

The team finds a Makarov PM on a deceased Spetznaz member in Season 4's "Chaos Theory", and identified by Bob as "Kirovsky(?) 9mm armor-piercing Standard Spetznaz Issue". In all likelihood, this is meant to stand in for an SR-1 Gyurza, though it is clearly a Makarov, with the grips being the most obvious giveaway. There is a noticeable goof when the team finds the weapon: in the initial shot of the stairway the Makarov is gone, it only appears during the close up shot. Other Makarovs are seen throughout the episode. O

Russian Makarov PM - 9x18mm Makarov

A suppressed Makarov PM is found on a deceased Spetznaz member in Season 4's "Chaos Theory".

Heckler & Koch MP5SD3

Heckler & Koch MP5SD3s are seen used by the Unit in Season 4's premiere "Sacrifice" (S4E01). Strangely, in season 4, the sound effects used are those of unsuppressed weapons.

Heckler & Koch HK416

Colonel Ryan uses the Heckler & Koch HK416 in Season 4's "Into Hell Part 1", though it is very difficult to identify clearly (the DVD extras provide a better view, albeit briefly).

Mark 18 Mod 0

Grey wields a custom built Mark 18 Mod 0 rifle in the opening scene of "Hero" (S4E15). It appears to be the same weapon used by Jack Bauer in Season 7 of 24. Despite being equipped with a red dot sight and magnifier, the reticle shown is that of a normal rifle scope.

DShKM Heavy Machine Gun (Browning M2 mockup)

A Browning M2 mocked up to resemble the DShK heavy machine gun is frequently used in the series. The machine gun was set up by Syrian forces in Season 4's "Into Hell, Part II" and fired by Mack in Season 4's "Switchblade".

Sniper Rifles

Remington 700 AICS

A sniper rifle frequently used by The Unit is a Remington 700 AICS. Mack also used this in Season 4's premiere "Sacrifice" and again in "Endgame". Sam McBride (Wes Chatham) is seen with this rifle in Season 4's "Best Laid Plans" (fitted with a Elcan Digital Day/Night scope, which is inaccurately portrayed not only as being a thermal scope, but as being able to detect heat through windows and curtains) and again in "Whiplash". The action is a Remington variant since the bolt is not an AI design. The folding stock hinge and adjustable cheek piece are visible in the close-up, so this would be an AICS 2.0 model. Also, AI L115 rifles are generally outfitted with Schmidt and Bender PMII scopes which this scope is definitely not. Also, unless the magazine has been removed (unlikely during a mission), the magazine on an actual Accuracy International AW/M will be protruding from the bottom of the stock. Visible is the paddle style magazine release in front of the trigger guard which would normally be blocked by an inserted magazine. This rifle is the same rifle used by Micheal Weston in season 2 of Burn Notice. The giveaway is the scope rings are the same cheapies seen on Jonas' rifle here. They should be heavy badgers or warnes.

AIG Asymmetric Warrior ASW338LM

In Season 4's "Best Laid Plans", Bob Brown (Scott Foley) is seen with a Gen 2 AIG Asymmetric Warrior ASW338LM modular sniper rifle in .338 Lapua Magnum while covering Jonas and Mack. Bob uses this rifle again during the standoff with Sam in "Whiplash".

Heavy Weapons

Cobray CM203 37mm Flare Launcher

M4A1 carbines fitted with the Cobray CM203 37mm Flare Launcher standing in for the M203 were used by Bob, Grey, and Mack on the mission to Iraq to rescue Betsy Blane in "Into Hell: Part 1" (S4E07) and "Into Hell: Part 2" (S4E08).

In "Whiplash" (S4E19), three M67s wired to the door of the auto dealership.

M26 "Lemon" Grenade

A terrorist attempts to use an M26 hand grenade before being shot in "Hill 60" (S4E16). Jonas finds a crate of them in Sam's storage locker. Sam later uses one to aid his escape, though strangely when he barricades himself in the auto dealership office, he is shown to have booby trapped the door with M67 grenades.

A terrorist tries to pull the pin, but is shot dead before being able to do so in "Hill 60" (S4E16).

Jonas finds a crate full of M26 grenades in "Hill 60" (S4E16).

CTS Model 7290M Mini Bang

A CTS "Mini Bang" is used by Jonas (combined with some drugs and chemicals found in the lab) in "Mislead and Misguided" (S4E10). During the standoff in "Whiplash" (S4E19), Sam holds one up to the window, calling it a concussion grenade. It should be noted that, though flashbangs are often erroneously called concussion grenades, the two are very different, as concussion grenades are much more deadly then flashbangs. Given the dialog of the scene, it's likely that the filmmakers intended for this to be an actual concussion grenade, and simply used a prop flashbang during filming.

"ALS" prop Flashbang

Sam McBride uses a flashbang grenade in the opening scene of "Hero" (S4E15). These grenades bear the logo of ALS Technologies (a real company which actually makes stun grenades), however they look nothing like any product in ALS's catalog. These are likely prop replicas.

Sam holds the Flashbang on Mack.

Crossman Air Pistol

Two Crossman air pistols loaded with tranquilizers were used by Afghan Tribesmen to incapacitate Jonas and Mack in Season 4's "Shadow Riders."

Wheelie bag carrying handle gun

In "The Conduit" (S4E04), Bob and Jonas had these weapons disguised as the carrying handles for their wheelie bags. It appears each of the square extendable rods were hidden barrels that each load one round, possible .22 or something small. To fire, they collapse the carrying handle forward into the smaller rod like you would a carrying handle of this type and it fires both rounds at the same time. I don't know if this is a real firearm, but it acts like one. Meant to be used to disarm armed men with real guns.
