OK, what does CBR mean? It sounds like it isn't very salubrious, whatever it is. You army guys are so into acronyms. God created the English language, with 1.5 million words and counting, for a reason. How many words of that do I know? I don't know. If it exceeds 150,000, I would be susprised. It might be less. And I don't have many decades left, to learn the remaining 1.35 million.
Chemical, biological, radiological. But its been a long time a long time since I was the Company CBR NCO. Maybe they call it NBC now. LOL
