We have had the 81mm since the 1970s, and I know it has given sterling service I am also aware of eg the lethal and blast radius, planning range etc but will not discuss these here When introduced it would have been intended for use against the Soviet hordes should they cross the IGB, but looking at the last ten to fifteen years, most warfighting has been of a different nature. There has been a great deal of warfighting in eg. Bos/Kos, and obviously the current main effort is in Afghanistan. Would the extra firepower of the 120mm now be a worthwhile asset? I know that in FRY one of the main causes of death has been the 120mm; it also seems that the range at which targets can be acquired in Afg can vary greatly, and do not doubt that the extra range of the 120mm ( 7-8 km ) could be well used. I have not seen the 81mm used with BULLDOG but there is already an OTS 120mm SP twin automatic mortar in use with the US, Canadians etc and it seems to me to be a logical; step to at least consider it. There is a tracked, armoured mark avaiable ( See here ) so it offers protection. The 81mm is a great weapon system; battle proven and effective, but AFAICT we do not have it in any mobile platform ( I'm deliberately excluding the ancient 432 series, but stand to be corrected. ) Double the blast / lethal radius; greater range; armoured vehicles OTS... Thoughts?
