Today is July 27!!!! A special holiday in DPR Korea (North Korea)

Read the description before downloading:

AG1= Cannon movement, use trim and VTOL controls
AG2= Firing stand (idk the exact term), VTOL down and you can turn it off while it's moving down.

History (From Wikipedia):
The M-1978 Koksan is a 170 mm self-propelled gun of North Korean design and manufacture. Very little information is available due to the secretive nature of the North Korean government. The designations M-1978 and Koksan were given to the type by US military analysts, as they first became aware of it in that year in Koksan, North Korea.

What is known is that it is a 170 mm (6.69 in) self-propelled gun of the open turret type. It was first seen publicly during a military parade in 1985. At least one example has been acquired by the United States, likely taken from examples captured by Iraq during the Iran-Iraq War.

The M-1989 Koksan is the upgraded variant of the M-1978 Koksan. The difference between the M-1978 and the M-1989 is that the M-1989 contains a cab for the crew to go inside while the M-1978 got only a hatch that is enough to make a crew sit on it.

Some notes from me:
The tracks are really not good to be used on bumpy surfaces as it makes the vehicle stuck on it. I posted this without any political reasons. The crew I put in the hatches are not that good looking but it does not affect the physics of the vehicle when you move it. This took me more than a month to finish as I'm creating this during the final days of our schoolyear, in short, I did my best to present this to all of you and an upvote will motivate me to become better on building things in the game and please criticize me well as I want to know where should I improve and apologies if I have a bad grammar here as I am not a Native English speaker.
