There will be no reinforcements, your main force is your T-72. Avoid it's destruction by any means!
We begin our mission on road. There is roadfork ahead. ISIS checkpoint is based there. The only real threat is AT team in far building.
On right side from spawn we can notice a smoking BMP. Tank crew stand next to it. They will tell you about the minefield (you can see it by debris and small rocks scattered around) and vehicles can't avoid enemy checkpoint and then they will join your team.
Take down enemy checkpoint. HQ informs you about one extra ISIS base on east. There is one minefield more on south. You can ride around it by risking your T-72 and deactivating few mines in most thin area by ridin on them, or to cut it straight through enemy base.
In later case send infantry first to detect and destroy enemy AT vehicles, when you will walk to enemy base too close, they will call for help. Enemy reinforcements will begin to attack from east. If you will destroy all enemy armor around base first, then NDF will attack without waiting for you to take care about enemy infantry. NDF squad and sniper squad will join your team then.
Further on south two enemy trenches are located. Squads with RPG are inside. On south end of map close to main road a huge trench with ISIS AT squad is holding position. Use smokes to flush them out.
On west from main road you can see small living complex. It's captured by many enemy squads, including two AT teams. Demolish threat by airstrikes, or just try to avoid this dangers completely.
There is enemy T-90 somewhere in desert in zone painted on minimap. It's constantly on move so you can't be sure where it is right now. All enemy forces in this zone are concentrated around fortified buildings. Scout the area with snipers or commander, to find exact T-90 location, and organize an ambush. This tank is though nut to crack, so use all available units to destroy it: right when tank will explode, mission will be completed instantly.
If you managed to smoke tank crew out, but tank still good to go after some repairs, you can capture it and drive it back to zone where you begun this missin. It will count as victory too.
