"They've been used for 100 years for a reason."

They're cheap, easy and they work...out to about 40 ft.

20 could take out an MRAP.

They are very effective against conventional vehicles and buildings, tents, supply dumps etc.

Especially if those are fuel and ammo dumps.

You think it would take 20? Many of the Resistance, guerilla and Viet Cong “tricks” need to be revisited.
