PENETRATION STUDIES OF ICE WITH APPLICATION TO ARCTIC AND SUBARCTIC WARFARE
Abstract : Impact tests were made on floating ice slabs with particular attention devoted to the mechanism of penetration. The range of values investigated for the basic parameters was: impact velocity, 8 ft/sec - 21 ft/ sec; projectile mass, 4.56 lb - 5.22 lb and penetrator diameter, 5/16 in. - 1-1/ 4 in.

The Surgical Management in War of Penetrating Wounds Contaminated with Chemical Warfare Agents [PDF]
Military surgeons in a future conflict may face the problem of wounds contaminated with chemical warfare (CW) agents. No useful guidelines for this eventuality exist-nor any assessment of the specific CW risk to such casualties or to the surgical teams operating on them.
