Twin chain guns
Nicknamed The Infantry Eraser, the planes are also good against lightly armored vehicles and structures, but useless against heavier opponents. The Yak is cheap and quick to build, but fragile against any form of anti-aircraft attack. Although cheaper than their anti-armor counterparts, they were fairly expensive compared to most ground vehicles.
The Yak was authorized for combat when Stalin ordered the elimination of "less desirable" dissidents within Soviet territory. The plane is armed only with a forward facing machine gun and attacks by strafing the target to "expend" its load. Their ammo is quickly lost, as the plane needs to retreat to its base after several strafes. Less favorable compared to the Hind for its weapon loadout, accuracy, and versatility, but the Yak's reload time is quite short compared to Hind's and it's quite mobile, enabling its survivability in a dirty battlefield. The plane is STOL (Short Takeoff and Landing) capable.
After the war, with the Soviet Air Force was forcibly disbanded, the Yak was relegated to the metal works to be processed into more "civilian" applications.
Slower and less armored than a MIG, the Yak is armed with a machine gun to take out infantry. They're also great for clearing mine fields - simply force-fire on a section of ground, and the Yak will destroy any mines in the area. The Yak has to be reloaded at an airfield after they attack.
Using Heavy tanks as a distraction when using Yaks to attack other buildings is a good idea since the Heavy tanks will attack the defensive units and keep them occupied while the Yaks attack all the outside buildings.
- Note that while Heavy tanks can be used to destroy an AA Gun, they will not occupy its attention while it is being attacked (it will still shoot at your Yaks).
