Colonel Leonard A. Izzo was responsible for justifying the adoption of the German Fox NBC Reconnaissance System as the Army standard, and he assisted in the accelerated training and fielding of this system during Operation Desert Shield.

Colonel Izzo coordinated the displacement of old decontamination equipment by new production models. He was instrumental in doubling the size of the Chemical Corps from 10,000 to 20,000 personnel and increasing the annual NBC budget to $1 Billion.

Colonel Izzo developed Chemical Vision 2010 and initiated an operational concept for domestic response to weapons of mass destruction. He supervised all Army activities related to NBC defense, including approval for CB defense protection requirements for Army installations and incorporating support for Homeland Security into the joint NBC Defense Program.
