Want to know what the U.S. Military buys? Here's the list! These are all products with a National Stock Number (NSN) that have been purchased by the U.S. military for their first aid medical kits. Some of these products are exclusive to the U.S. military but many are available to you. For U.S. Military personnel, you can purchase these products from H&H Medical's DAPA Contract (Contract No. SP0200-05-H-0034) or our ECAT Contract (Contract No. SPE2DE-14-D-0007).
