Absolutely correct.....take the easiest target that gives the biggest bang!
The other side of the equation is to take the easiest target over the harder target as most insurgents prefer to run away and fight another day unlike their radical Islamist brothers.
A .50 caliber rifle alone is a most effective means of dispatching soft targets....it can be done from ranges up to 2400 meters (if a true professional is pulling the trigger as did the Canadians in Afghanistand) and up to 1500 meters by ordinary marksmen.
Add in the mobility of the lone rifle....a fast canoe...and the vast network of canoe kindly waterways and there you are!
I figgered the Oso would have been into orbit by now without the MEND bunch being involved!
