Division 2 studied theoretically and experimentally the effects of explosive 

 waves in air, earth and water and the effects of explosions and of projectiles 

 on targets such as armor plate or pillboxes. It also handled a number of 

 problems bearing on the design of specific weapons as a result of the basic 

 knowledge it acquired. The original emphasis was on defense but with the 

 progress of the war the effort was focussed on determining the best means 

 of destroying enemy defenses and industrial targets.
