If you are planning to keep the tool on your vehicle, given your occupation and area stationed, then a proper axe is your answer I think. Long handle, heavy duty.
Go for razor sharpness like GB Felling Axe, or one made in the USA, hickory handle, the real deal.
There are so many things to do with an axe on a rural environment, from forced entries on old country houses (and not only) in cases of emergencies, to clearing back-roads from reasonably sized fallen logs/trees and making repairs etc.
Now I have the bk9, and it is an excellent chopper for general use in camping/outdoor activities and if this is what you want, go for it. A monster of a knife. But this is what it is. A big knife.
I would go for a proper axe, and EDC a razor sharp small 4" fixed hunting blade, like a Bark River beauty, witch I would take off me only when I went to sleep. You will use it for everything. And it will look fantastic, hanging next to a 9mm.
