Hi, What's the best stuff to send in a Christmas care package to a Marine who is either on a large deck Amphib or on the ground in the mid-east? Im more inclined to send functional stuff, versus cookies and toothbrushes. I was thinking like tools, stuff to help clean weapons and equipment, etc. The person is not family. Ive heard that compressed air, fine/small brushes and similar are desirable for keeping things clean. Thoughts/recommendations? Thanks!
