Sounds like you're ready for the battlefield then. In case you don't know, the only dressings that need to be sterile are the ones touching the wound. It is OK to place non-sterile (but obviously new and clean) dressings on top of the next-to-wound sterile one. The non-sterile outer dressings are just fine for absorbing blood or applying pressure. You can save some money that way. Sterile costs a lot more.
