Consider the possibility that you're the clueless one here. Pitched battles are generally horribly inefficient for insurgent forces; they're not used to fighting in formation or doing sophisticated combined-arms attacks, and if they just rush their target as a mob it's easy to shoot lots of them with a machine gun. A small force of 20 people is easier to train, coordinate, and deploy and can be much more effective once they learn hit and run and basic ambush tactics.
