To adapt a kit just for military purposes sounds more like what you would have on a deployment, but perhaps trying to build something smaller. Is this a kit which you can carry around on Post?
I am a Vietnam-era veteran and was on a Mobility Team twice during my eight years of service. So I always leaned toward gear in surplus stores.
Before I became educated about titanium gear, improved BOB contents and lightweight Arc'teryx backpacks, I used mostly surplus gear, such as a BOB and general hiking setup; put together in a large Alice pack with metal packframe. I packed a stainless mess kit, steel canteen cup and standard GI canteens, Nesbit stove, FAK, FSK, food and surplus BDUs. After a couple of years of backpacking this stuff, I realized that the weight of this sturdy, durable and dependable gear did little for my middle aged back. If I were in my twenties, it wouldn't be so bad. So I upgraded everything from outdoor and alpine shops.
My general backpacking items are similar to what you will see on many posts regarding BOB contents, so I won't be redundant and create another list.
