If SHTF, Think Rifle Squad:
-One or Two Bolt-Action 30-06s w/Good Variable Scopes for Long-Distance Work
-Several .223/5.56 Types for Firepower Base
-Coupla Pump Shotguns w/Sack Full of Various 3-1/2" Loads for Street Sweeping and House Cleaning
Each Guy Bring His Own Favorite Gun, plus Possibles Bag of Miscellaneous Goodies.
If SHTF, Lone-Wolf/Rambo-Style won't go very far.
Just a Thought.
And--A Good, Strong Squad Leader. [Think of All the Serious Good NCOs You've Known. Tall, Lanky, Shaved Head, Ears Stick Out............And They've Got that STARE that can freeze a Grunt in His Tracks.]
