If you were serious in a civil war, any weapon is an arm. If you didn't use such weapons to take out large enemy....(i.e. regular US) formations, your little revolution wouldn't last a week.
somebody forgot to tell the Vietcong that in the 60's and 70's, the Afghans in the 80's, and some folks in Iraq in the 2000's...........
A determined, indigeneous force, can--and history has so demonstrated--wreak havoc against a enemy with superior numbers and firepower.
