Nice work on the mission! I've some new suggestion, but remember, I'm not forcing anything on you, it's just my thoughts.

1st: Delete items from BTR outside

2nd: Delete some ammo from ammoboxes near traders. I would leave only 5mags for M4 and 5mags for AK +maybe some glowsticks to give player some challenge. When you leave that much ammo, players can sell almost everything to traders for +1K and then you can buy every highend item from them, right from the start.

3rd: Delete items from Hawk helicopter (I don't know if this would be compatible with heli respawns).

4th: Reducing ammo and weapons in ammoboxes which are scatered on the map. IMHO bandit camp has too much ammo (70mags is overkill)

5th: Give bandit base some more love = 2 bandit patrol outside of base perimeter, others in fixed position in the industrial building (disable AI path). Maybe some intel secondary intel...
Some other small bandit base somewhere.

6th: Other enemy base with PMCs. Military base on the hill could be good place. More rewarding loot (suppressors, Optics) and small helicopter.

7th: Recruitable AI in the base, 1-3 guys. Without gear, so you have to equip them, if you want their help.

8th: Disable AI path on guards near HQ entrance, as one of them went outside of the base in one of my playthrough.

9th IMHO I would turn off vehicle patrols (Namalsk is quite small island for them).
+ I would reduce ravage vehicle spawn (more challenge)

I completed the mission rather fast last time. Mission could benefit from additional final task. Collect like 5k money as extraction money, this will unlock vehicle which you can escape Namalsk (big boat or locked and damaged plane on airfield). Task could be given to you by another character on the map. TO BE CONTINUE in next mission on another map...

@Hans(z) First off thanks a lot for the feedback, i`m really surprised that my first mission turned out so well, i will definitely be making a series, anyways thanks for the suggestions.

@Hans(z) Also don't worry about forcing anything, a lot of things on this list are really good ideas
