I can't finish even 1 mission in compaign mode. If the primary goal is to clear the area i kill all that moves in this area but still this does not count and overall mission is failed. May be i do something wrong.

Which scenario? Try asking here: http://pedg.yuku.com/

First mission of the German Africa compaign. Where you need to clear the Toum station

Sorry for the late reply. I do not visit this forum as much as I once did.

That is a common problem. Somewhere there are infantry hiding in a building. They can be hard to find.

If you do not have the feature turned off, you can look at the game map an see if any enemy is spotted in the area. You can let the AI fire at will. You can click on buildings to see if a target marker is displayed.

If the infantry panics and runs out of town, the goal is not reached until 80% of time expires or you hunt them down and eliminate them. If they have enough time, they will try to return to the station.

Thanks for reply. I will keep trying

Worst case scenario is that you can edit the scn file with any text editor (edit : so you have heavy artillery to flatten the area) and use heavy artillery to flatten the station area.

i have the same problem. i cant finish the mission because it wont accept the goal "clear toum station", even if i kill everyone around. "show every unit" (even hidden ones) is switched on, and i killed them all twice.

what in the .scn do i have to change to get artillery?

As far as i can tell you have to kill everything that is on the whole map.
There are 2 AT guns and 2 infantry units south of the start position, in Chaib. And there is Platoon Alpha attacking from Toum, after a successful attack they will retreat to El Bey (Stop them).
Inside Toum there are about 5 infantry units, some with Anti tank weapons. And there is Platoon Bravo coming from El Bey about 10 minutes before the mission ends. My mission was successful as soon as i killed all that. Spotting the infantry units is impossible without enabling "show all units on map" in realism settings.
Also btw i recommend tripling the damage of all weapons done to infantry, they take a hilarious amount of shots.
