A soldier, combat or regular, needs a GP knife adaptable to numerous useful purposes. Fighting with a knife is way down that list. An "issue" knife must be adaptable to all soldiers, who may get a day of training with it during Basic. Even Specops troops don't spend a lot of time on martial arts training, so many train on their own. Today, weight and bulk are more critical than ever. Soldiers wear Kevlar helmets, vests with ceramic plates, 1-2 liters of water, rifle, and maybe pistol too, ammo, and a host of other necessary gear. When I could shave weight, I would. When I could carry more, I added ammo. That being said, I'd opt for a lighter, faster
utility blade. Ka-Bars, USAF survival knives, Randall model 1/15/18 series knives are utility blades, not primarily fighting knives. Fewer solders, even in the Specops community, need a Fairbairn-Sykes, Gerber Mk II, or Randall model 2. My personal choices in khuks for military use are:
- GP: 16.5" WWII (mine's a village model with blued blade).
- Combat: 18" Sirupati (again, mine's a 17" village model with blued blade. Going to war, I'd also blue the pommel and bolster.
- Breaching: 16.5" Chiruwa AK (not the best fighter, however).
I think the 16.5" WWII, or even BAS, best as an "issue" khuk. I'd probably choose the Sirupati, since it will do everything I generally ask of a military knife. If I was involved in rescue or breaching operations, and traveled by vehicle, I'd want one Chiruwa AK with the team, in the vehicle.
Look to the Brits and Gurkha Bde. They are the real experts. They've carried a 15" BAS type khuk with an 11" blade, essentially since WWII. I expect there's a good reason. Most of the WWII models I have are lighter than HI equivalents (HIs are thicker at the spine and have more grip). The WWII blades are generally 12"-13" long, and about 1/4" at the spine. A K-45 feels light and fast - and right. My WWI khuks may be more in the 13"-14" range.
And then you have to consider what's acceptable to the command. They can be funny about individual modifications to field gear, or haircuts. Specops has a lot more latitude in this area.
