Fondly I remember CBR training.

My test was this simple scenario.

Our squad is walking in the forest when a chopper flies over. A must settles from the sky. Suddenly the soldier near you starts gagging and puking up blood. He falls dead at your feet. What do you do?? The instructor asked.

I remarked in a very droll way.

Kiss your ass goodbye as you just walked thru the same crap as he did.

His stare was priceless.

I said " Oh right......yell GAS put my mask on THEN die gagging in my own puke wearing the mask."

A drop of VX the size of Lincoln's eye on a US Penney will kill you in seconds. Inhaled or absorbed.
