5 guys acting as a guerrilla combat force is all you need to create an "enclave." You don't create an enclave by holding ground and setting up green zone; you create an enclave by creating an area were socio-political dynamic allows for popular support.

Those supporting non-combatants will become a observers, feed you intelligence, let you sleep on their floor, & allow you a few moments warning to Retreat when the enemy advances. I'm comfortable anywhere; in the city, in the suburbs or in the woods. The biggest sin in combat is being predictablethe US Army and Rednecks have the same philosophy. Adapt & Over come for the Former and Get-er Done for the latter. So Getter Done adapt & Over Come... Hey I just had T-Shirt Idea... lol
