(It was my fault, I forgot to change the title

)
@ofp addict
Thanks for the great feedback.

And it looked like I forgot to change the thread's title.
The newest version is v1.3, which I had to upload to a file sharing site due to the large size.
Is it the one you played this one? Or the v1.25?
Due to my CPU spec my OFP runs slower with vol-fog and night time so decided to go in during the day and not stealth.
I think it would be better to maintain stealth, so the engine won't have to handle many soldiers in the combat state. I think stealth is less CPU consuming.

And do you noticed that you can
turn off Vol-Fog and the Random Weather script from the radio menu?
When I can afford a decent new upgrade I will try stealth and night time OR probably play ArmA
You better play ArmA 2.
1000 Bizon rounds later

NOTE One shilka in the centre of the town was upside-down-on-its-roof ?
The alien, who was doing push-ups, must have accidentally done this.

Just kidding, I've fixed that problem in v1.3.
After many attempts I destroyed the last shilka and escaped again using the way I came in. From the North. I then followed (a double steel fence with empty watch towers) and came across a Ural on the road, Shot the driver and drove on to the safety of the blackhawk. Then I boarded feeling like an accomplised veteran.
If only you've maintained stealth, you won't have to deal with some of the tanks as well as the Spetz Natz.
1. Some kind of enemy presence patrolling the long steel fencing with the fuel station (north-West)
I'll try to add it in the next version, v1.35 or v1.4
2. JAM3 version
I thought about adding JAM3. I'll add it in the next version.
(Should I give the players HD weapons too?)
And I also thought about using BAS Rangers,
but I think it is unwise to force players to download a 23mb+ addon just for the three specops,
and more importantly, something is wrong with their arms when they prone, they just didn't look cool.
I found lsr_weapon pack much more interesting, as it contains silenced snipers. but it alone is more than 70+ mb size. And I can only use it on the three specops unit.
3. T72 crew (turned in)
Frankly, how do I make them turn-in? And I suppose they are turned-in while in combat, aren't they?
