Thanks to a high amount of explosive mass, the M66 HEAT shell is extremely effective against enemy light tanks and open-topped vehicles at its BR thanks to the overpressure mechanics, making it a do-all kind of ammo for the 75 mm Howitzer.
Do not angle your Tiger II (P) turret with the side with a cupola bulge, as it is pretty vulnerable. If you decide to angle the turret, use another side.
Use the SC1800B or SC1000L2 bomb for effective close air support. Make sure to lower thrust to 50-60% and apply airbrakes. Aim slightly in front of the target (see image) and quickly drop and pull away. Best used on heavy tanks and/or groups of enemy targets
Having troubles dealing with the ground targets? Use the 6 RBS-82 rocket load-out, lower the thrust to 50-60% and dive straight down to penetrate them through the roof.
