The best way to use the Jagdpanther's armour is to find a small hill where you can angle the front of your tank upwards to where your gun can still fire back at incoming enemies, but also have your frontal armour maximized (due to the fact that your frontal armour will be at a higher angle for incoming shells, which will dramatically increase the odds of a shell ricocheting. However, heavier and/or higher velocity shells (SU-152, IS-2, T29/T34 are examples of tanks that will not experience this problem very much) will not have this issue due to the weight or velocity compensating for the increased slope and penetrating anyway (that is not to say that these types of shells cannot bounce, it is just much rarer due to their weight and high velocities.) 76 mm M1 from the Sherman, 88 mm L/56 from the Tiger I, 90 mm M3 from the Jackson/Pershing) will have issues with shells ricocheting off the front plate due to the angle of the tank's upper frontal plate. The armour of the Jagdpanther in itself is average but can be utilized to become extremely effective due to ricochet mechanics.
