| Notes | The Estonian army adopted the 37mm Rheinmetall as their standard anti-tank gun. The military had seen how important it was to organise a strong anti-tank defense and after various trials they went for the Rheinmetall. They managed to purchase 44 of these guns between 1937 and 1938 and they differed from the version adopted by the German army by having a longer barrel. They were the main gun and issued to all of three anti-tank companies. |
