strength in numbers??
if it's TEOTWAWKI....
two crates (5 rifles ea.) of Yugo SKS with ~5,000 rounds of mil. surp. would enable you to train and arm a 20 ~ 30 man militia to a minimum proficiency level.
8 hour shifts, turn over rifles each watch rotation, 10 armed men on watch 24/7......
all this for the price of one M1A, seems like a good plan and a lot of bang for the buck.
add two that several "members" personal shot guns and odd cal. weopons, hand guns, etc...
Word would get out quick and your neighborhood would become known as "not an easy target"
(not that I really wouldn't like an M1A)
