Welcome to the Yard jforbush and thanks for your service. You should be able to find something in the after market for a fair price. Although the S6 is close in size to the BK7 you have, I really like the feel of the S6 in hand. It just feels good, probably not all that helpful, but it's true.
Rumor has it that Dan has something else in the works soon from the Yard and who knows, it may be right up your alley. Never having been in the military, I am not sure what tools would be best for what you do, but for a bigger blade I like the S6 (.25" stock), for a smaller blade (which is usually what I carry), I am really liking the recent release, the Yard Keeper Combat Grade (3/16th" stock) aka the YKCG or the Dumpster Mutt LE (.25" stock) aka the DMLE. Although LE versions are shiney which is probably not a good thing for you.
The S6 is the 4th blade from the right and the DMLE is the second blade from the right.
