A good friend of mine has been accepted into the Marines and is going off to bootcamp this Spring, and I want to know what sort of going away present I should give him. He already has a wicked knife and a good watch, so those two options are taken. My price point is anything under $70. So, what should I get him? (especially looking for answers from someone who has been in the service before) (He's hoping to become a scout sniper, he's got everything going for him including the 20/15 eyesight, hunting experience, and short stature)
