| Notes | The 170mm K18 was a heavy gun which was developed for long range counter battery fire. It was issued at Corps level and turn out to be one of the best weapons of its class. The gun was mounted on the same carriage as the heavy 210mm Mrs 18 and could be traversed 360 degrees. It fired a heavy shell which had the same explosive power as the round fired by the larger 210mm. It could be either broken down into two loads or kept whole for transport over short distances. It was well respected by the allies who treated any captured guns as prize possessions and duly turned them on their previous owners. It was first introduced in 1941 and served out the war. |
