Is there any merit to the BFG Overlord filling the "patrol" pack function, with a BFG Micro piggybacked into the beavertail to fill the "assault" pack function?
Krax, I read what you mentioned above, right after I revisited the blurb from Tack above. I've had this context in my mind of using an assault pack versus a patrol/3-day pack, based on mission, and not in the context of using an assault pack IN TANDEM with a patrol pack, where the user moves to the ORP, sets security, and then employs the assault pack to move further forward and conduct the next phase of the mission (objective surveillance, assault, contact patrol to a village, movement-to-shura, ambush, etc.). I think we need to consider that flexibility.
Desert01 just shot me an email that lays out a concept for an assault load (he uses a different term), and it looks a lot like the back of a shortened H-harness/belt order concept, except it doesn't ride on the waist, but on the bottom and kidney areas of armor, where their often is unused space. Distributing load to those areas has to make it ride easier on the wearer, thus a win.
I guess we could set the assault pack inside the patrol pack. I'm not sure that shifting the center of gravity further away from the body (when an assault pack is docked on the outside), without benefit of a rigid frame, would endear that patrol pack to the wearer after a few klicks, armor or not.
I can zip bergen side pouches to my Karrimor Sabre 45, and unzip them, connect them to a yoke, and use them as a field expedient assault pack. I'm not sure if that was the intended function, and it's fairly crude, but it probably gets the job done in typical Brit fashion. My whole point is if the additional assault pack load was spread somehow around the sides, top, or bottom of a patrol pack, zipped off and then tossed over shoulders or clipped in to one's armor, we might be able to avoid the COG issues. Without a perfect combination of straps, COG, and maybe even potential waist belt relief, patrol packs can still suck on a long movement; keeping the COG in our favor would seem to be important.
As an aside, I had a conversation with the OIC of our Basic Reconnaissance Course, and he confirmed that the standard for long-duration reconnaissance ops is 7 days. You might be down to the guts of one MRE a day and filtering your water, but they plan for 7 days. That's where we have transitioned well into our concept of the 3rd line of packs...the ruck.
