Loc-Out --
There's quite a market in military HF manpacks, but they're expensive. They turn up on eBay (very expensive), on amateur radio sites (not so expensive) or at amateur radio rallies (you can get lucky, but you have to be able to cope with ham rallies. These can sometimes seem like a home for the terminally bewildered let lose at a Harrod's sale).
Have a look at

if you're keen. A much cheaper, more effective, easier and more fun alternative is to get a Yaesu FT-817 portable HF/VHF/UHF transceiver -- which in any case uses technology that Yaesu developed for its mil range. Costs £800 in the UK or £600 if you shop around on the Net (Greece recommended -- US prices and no import duty).
I'll get me anorak...
