War trophies are allowed. You need a commanding officer's approval and a "DD Form 603-1" filled out. This form will be presented at customs, with the war trophy. Failure to present the form, results in the item being seized.
It's common belief that soldiers can not bring war trophies home, but this is false. A well written request to your commanding officer, should get you his signature. The trick is to word it, so it sounds like an award or commendation.
We received Iraqi Ak-47 bayonets, for training their soldiers in close quarters combat.
The inscription read:
This token of exemplary service to the people's Army of Iraq, is presented to the members of the 3rd ACR, 1/3 ATRP. For meritorious service, during the joint training operations, in the Niniwa province of 2007-2008. The units actions bring credit upon their country and uphold the highest standards of the Army.
Another trick is to tack it on a plaque, make sure it's inscribed to sound like an award. Even, inscribed as "presented by some local Iraqi police Cheif or officer."
Oh, and always remember to get one made for the commander. Not signing yours, means he can't get his. Well, he could...but it would be a dick move and he'd have to keep it on the down low. While your at it, it's always good to grease the tracks by getting one made for everyone up your chain of command, all the way up to the commander. This eliminates the favoritism factor, that could hurt your chances of getting the sign off.
When you get home take it off the plaque and have fun with your new trophy.
On a side note, Anyone notice how roomy the center of a V-Vac filter is behind the Bradley engine?
It looks like this, but in the shape of a V.
