To be historically correct, just stop and fire. Early in 1943, some 75mm Shermans were fitted with a Gyro-stabilizer, however, it was very controversial and most crews deemed it worthless and left them turned off. The 76mm Shermans did not have the gyro and had no power elevation/depression for the main gun. The M-5 and m-5A1 Sruarts did have a decent Gyro and the M-24 had an improved model. )( I went through Korea in an M-46, hand cranking that 90mm up to hills and down to valleys, and power elevation was always wanted.) No gyros or power elevation was included in the M-26, 45, 46 and 41, the first good tank with all around turret power was the M-47, then with the 48's and on, everything was powered, but no gyro. The M-1 Abrams and all newer tanks and bradley have everything with very good shott on the move gear. German tanks never had a gyro and Russians, until the later T-64 series also had none.
