Official Tactics
Block the road with the tank and use the artillery to attack. It’s a good plan to move the artillery in tandem with the tank to support it. Don’t allow the tank and the artillery to become separated.

Guide
This is another mini-tutorial battle, with the first taste in the use of indirect units and the explanation of ammo, fuel & terrain advantages.

To start off with, use the tank to attack the infantry unit. Your tank is out of ammo so it can only use its secondary weapon, a machine gun. But tanks use their machine guns anyway on infantry type units regardless of ammo so it still pretty effective. Next move the artillery onto the forest so it’s on prefect position to attack next turn. Finally move your infantry unit onto the mountain to attack the enemy’s infantry unit, which should be destroyed now so your infantry unit levels up.

In the next turn, your enemy will move their 8 HP recon unit to attack your infantry but can’t kill it. During the start of your next turn, you will need to move your infantry unit to the ruins in the middle of the mountains. A cut scene will take place.

After the cut scene, it’s time to get back to the fight. Fire your artillery at the top recon, destroying it, and use the tank to attack the bottom recon, the one that’s next to your tank. During your next turn, your enemy tank rolls along closer – and unlike yours it’s loaded with ammo so better attack with your artillery (leaving it with just 1HP). Again, use the tank to attack the recon (the only one left now).

Now the enemy tank drive right next to yours isn’t that convenient - time to destroy it with your tank. In some cases, it may take two turns but often you just kill it. Now use your artillery on the motorbike. It will be a good idea to move your infantry unit to the middle mountain, the one that’s just above the ruins. During the next turn, the motorbike unit will try to kill your infantry but it helps that you’re on the mountain.

Time to deal the winning blow with either the infantry unit or your tank; you know what to do now. Tada!
