Finnish fighter tactics lectures 1943...
**
During the grouping-up everyone must keep their eyes open, so that the enemy fighters that could be lurking around over the airfield or nearby cannot surprise you. For example, at Hirvas Air Base in the summer of 1942, four Tomahawk (P-40C) fighters surprised a Brewster flight taking off. The Brewster pilots should thank only the poor shooting by the enemy for their survival. The Russkies had been waiting for a good opportunity to bounce in the low clouds and couldn't have got a better one. For example, one Tomahawk shot at a Brewster taxiing on the ground, but shot so poorly that the plane didn't suffer a single hit.

The LaGG-3 is not especially agile in dogfight. It usually tries an outflanking approach from up and behind, shoots and pulls up. Likes head-on shooting. The tail has a heavy armour. When attacked it tries to evade with a quick half aileron roll to either side. The most vulnerable points are the engine and the radiator below the aircraft.
The LA-5 is an extremely agile and fast fighter. Similar hooking tactics as LaGG-3 thanks to its good climb performance. The method of fighting: usually an attack in sections from above; the flight leader fires first and his wingman when the target is evading.
In addition to aforementioned planes the enemy uses American types, such as the Tomahawk and Kittyhawk, which are not as good as the LA-5. They are about on a par with LaGG-3 but more vulnerable.
