The M1978 Artillery is first encountered during the first contract; Ante Up, where a battery of 2 guns is being commanded by the Two of Clubs. The M1978 is used by the Korean People's Army for bombardment of enemy targets at long range and is typically set up in well-guarded positions to the rear of the front lines. An open-turret design, the M1978 is a rotating 170mm cannon set on a tank chassis; it offers no protection for the gun crew at all.
The gun can be aimed forward by the player as if it were an anti-tank weapon.
As it is North Korean hardware, destroying these weapons nets the player $10,000 to their account.
The M1978 is based on the Koksan M-1978, a self-propelled artillery piece designed and manufactured in North Korea. "Koksan" is a name given by American military intelligence, as it was first discovered in Koksan, North Korea. The M1978 "Koksan" is built on a Chinese Type 59 tank chassis, has a crew of 8, and saw use by Iran in the Iran-Iraq War.
- Although it is a self-propelled gun, the M1978 cannot be driven and in fact is never seen moving.
- The gun itself is shares the same name as the M-1978 self propelled artillery it is based off, but it looks quite different.
