One huge issue for the military today is that they do a lot of crowd control. Generally no one is going to grab your rifle, no one either go for your handgun, but a knife unsecured is asking for an idiot to pull it and stick you with it. The other biggie is weight. Fully loaded there is enough stuff to carry. If you are going to carry something then it had better be useful. A folder or multitool are.
Expensive kit have a big negative in that they can course hesitation by the pure fact of their ticket price. Frankly, inexpensive, replaceable and repeatable is better. A light weight, 7", pointy pry bar, with an edge, is plenty for getting mud out of tank tracks. You get issued with mine probes and KFS.
Anyhow, the above has been said often enough.
Recently I gave one of our Special Forces a Skrama to take for jungle training. In the jungle then a machete or golock or Kukri are pretty mandatory. The Skrama would fit the bill. I'll know in a years time if: one he took it; two found it useful, or three put it in the skip next to the boat house. The latter I doubt, but it will be interesting enough if he actually deploys with it or leaves it at home. He knows his stuff; its his call.
I was a Cold War Soldier and carried a Chris Reeve Project II on my battle order webbing; it was the least used tool of all the knives I carried. Its was better utility wise than the Cold Steel Master Tanto I had for a couple of years. I would probably carry a handgun first now. The Cold War was when body armour was NBC kit, whereas now body armour is for defence against IED's. The real truth why I carried a big knife was that I have always be interested in the survival, bushcraft and E&E. But heck with a bit of knowledge a SAK Huntsman would surfice. I am a woodsman at heart but many of my fellow soldiers just preferred blowing things up.
I know you really wanted another answer, and not this angle... again... My one suggestion would be, if you are determined to splash the cash, is to look at Survive Knives GSO's, or the small thinner stock Busse's. Both will go walkabout before they break.
