New options for the secondary missions:

- capturing of high ranking prisoners (destroying the enemy A0 unit) to get the information needed for anti flak strikes (other uses also possible).

- finding and destroying an ammo dump which contains flak ammo (reducing the ammo available in the primairy mission and giving warning of the presence of flak in the pre-mission briefing).

- intercepting an enemy convoy transporting the flak guns (reducing the flak available in the primairy mission).
