"The Guard Post" is a Korean movie involving story of a mysterious death of an entire platoon located at Guard Post 506 (GP506) near the DMZ, a border between North and South Korea.
The following weapons were used in the film The Guard Post:
The Daewoo K5 pistol is seen carried mostly by Sergeant Major Noh and Staff Sergeant Yoon. It is also seen in the flashback in a fight between First Lieutenant Yoo and the medic, where Yoo uses it to shoot the head of the medic.
Dong-San K1, airsoft replica of the Daewoo K1A, is seen carried by several soldiers in the film but is never seen up close or being fired. The difference from the actual Daewoo K1A can be seen by the lack of take-down lever behind the rear-sight, square pistol grip, larger and rounder trigger guard, higher bolt placement, straight bolt-handle, and the lack of magazine fence.

Note the larger trigger guard, squared pistol grip, higher bolt placement, and the lack of take-down lever behind the rear-sight, showing that it is an airsoft K1A replica, not an actual Daewoo K1A
Daewoo K2
The Daewoo K2 is the weapon that is shown the most in the film, and is used by all Korean infantry soldiers in the movie. It is the main assault rifle of the Republic of Korea Army. The weapon is seen with both rail system and optics on and without. Almost all of the optics and rails used are manufactured by the Korean Dong-In Optical Co.

Note the flying brass, which happens to be blanks. In this sequence, he doesn't shoulder the stock but fires with incredible recoil-control. He also doesn't even blink when he fires!
Ja-Seng K2 airsoft replica
When the actors aren't firing blanks, they are mostly seen with Ja-Seng K2 airsoft replicas, which would be much lighter and safer for the actors to handle, and can be used without an armorer present on the set. The difference from the actual Daewoo K2 rifle can be seen by the straight bolt-handle, smaller rear-sights, awkward-shaped folding-stocks, thinner front-sights, lower bolt placement, smaller bolt, gap between the receiver and the hand guard, and the lack of swing swivels on the lower barrel.
Trivia: The Ja-Seng K2 airsoft replicas are all-plastic, scaled-down, pump-action airsoft replicas. They are known for their bad quality: lacking bolt, smaller scale, and bad details. It is quite amazing how the prop-designers of this movie improved the quality of these airsoft replicas up to this much.

Note that it has Dong-In Optical Co.'s K2 rail system and a T3 dot sight, which would not be possible to put on the normal Ja-Seng airsoft replica. The armorers somehow managed to attach rails on these airsoft replicas.Error creating thumbnail: File missingA frightened Korean MP soldier holding the Ja-Seng K2 airsoft rifle.

Note the shallow bolt, straight bolt handle, lack of sling swivel, huge gap between the receiver and the hand guard, and the overall smallness of the rifle. There is also a hole in the hand guard, which was originally for the pump-action system of the typical Ja-Seng airsoft replicas.Error creating thumbnail: File missingA Korean MP soldier holds the airsoft replica on another soldier. Apparently, he can't aim down the sights because the stock is too short, being a scaled-down model. Note the thinner front-sight and smaller rear-sight.
Machine Guns
Fake M60
A mocked up M60 machine-gun can be seen when Corporal Kang is explaining about the North Korean GP 300 meters away to two newcomer privates. He accidentally discharges the weapon, which results in a burst of machine-gun fire from the North. Corporal Kang shows the M60 to the newcomers, calling it as the machine-gun that came out in the movie "Rambo". However, this M60 seems to be a fake M60 with front-sight taken from AR-15 series and a thick cylindrical part of the barrel sticking out of the hand guard. The gun also apparently fires from a closed-bolt position, where as actual M60s fire from an open-bolt position. It also apparently does not eject ammunition belt links when it fires. It is unsure, however, what the base-weapon of this M60 mock up is.
The K400 grenade can be seen equipped on soldiers throughout the movie. It is used at the very end scene where it is used as a booby trap that blows the entire GP506 complex. It is a South Korean made hand grenade developed in 1975, and is still in use, although in some platoons it is being replaced with the K413 hand grenade, a smaller and lighter variant of the K400 but has the same lethal range of about 10-15 meters. The design is inspired by the M67 hand grenade, although the design has changed to be more lethal and able to be thrown further, and to produce about 1,300 fragments when detonated.
The 1/2 Pound TNT Block is shown at the end sequence with the K400 hand grenade being used as a booby trap. Noh setup the booby trap so no one would exit the GP506 alive, avoiding the spread of the infection.
