I would be interested in knowing how many of these folks were involved in the destruction of captured enemy ordinance.
Yeah.. that was my other thought too, but then again if it were an airborne agent once those shells were destroyed I would imagine one of two scenarios occuring...
1.) when the shells were destroyed they would have been bundled together and laced with c4 and det cord... in the ensuing explosion and fireball I think any of the airborne virus or agent would have been consumed or sterilized by the fireball and heat created by the explosion.
2.) If there were a release of an agent into the air after destruction, I would think it would affect others in the geographical area...but that could vary based on weather conditions humidity etc...
Excellent point though.
