I see in the game the us m1917a1 machine gun with short mount and tripode,     but the silhouette bmp  appear with hight mount tripode similar as the Vickers .   Is this mount, fexible and can take the low or hight position, or is this a bug with the weapon?  This could also explain the "bad" position on the knee taking, from the crew, this position will be possible only when the weapon has a high mount and tripode. Or this is a choice from BFC to use
