Hello there. I've been tasked with devising a plan for a mobile HQ for a specialist unit. Unfortunately we have not recruited a QM yet, and I know little about tents other than those used in infantry. My basic plan, based on a BG HQ, was for a cross shape made up of 5 12x12 tents, one in the middle and four making the crosses. However it appears this is not big enough. Does anyone know the sizes of larger tents in use in the army? And can anyone point me to info on design of such setups, SOPs etc. We also need a large briefing tent, and even jooining 2 12x12 isnt big enough. Help!
