I'm all for firepower and tube launched PGMs, and understand that the 120mm EFSS will take over from the 155mm, but what about minmum safe distances and ammunition resupply. The 105mm guns and 81mm/60mm mortars still have their uses as they can provide more intimate fire support, especially if the enemy are 'hugging you'. A comapny sized untit cannot provide for all the fire support it needs by itself, but due to its size can be overrrun, or elements of it.
