Don,

Just what are the "hard facts" that are at variance with the Sgts "feel good propoganda". You don't need to know everything about chemical and biological agents to survive them.
No, he doesn't cover exactly what anthrax looks like or does.
What he does tell you is how to avoid contamination from a variety of agents, good, general rules of thumb. And that's what's needed. A Bio-attack, when and if it comes, may take any form and the specific preventive measures used for one may not be effective for others but general measures will be.

They are Govt. agencies and as such depend on convincing the Appropriations Committee that their work is absolutely vital in order to receive funding.

We all need to be aware of that.
