|Could someone enlighten me as to why Western Armies adopted the 155mm caliber weapons?
Throughout WWI and WWII 152mm (6 inch) was used by everyone, from navies to armies. Whereas the East kept this size, why did NATO feel the need to move up 3mm's?
Also, why does the 152mm weapon have the reputation (as far as I know), of shooting the larger shells, do they have longer cases or something??
