Lets see, I've been through 4 direct hits by tornados, one of which was an F4 that leveled Altus AFB in 1984, the flood of 1993 on the upper Mississippi, the Blizzard of 95 in New Jersey, hurricane Floyd and Isabel, and 1 small earth quake while in Petaluma CA.
So yeah I've been in the middle of my share of natural disasters and unnatural ones as well, Desert Storm, and New York City right after 9/11 (deployed the morning of 9/12 for 45 days of Port Security)
So yeah I do have an idea, thank you very much.
