5. Travel light and harden your Combat Service Support. You will be weighed down with body armor, rations, extra ammunition, communications gear, and a thousand other things. The enemy will carry a rifle or RPG, a shemagh, and a water bottle if he is lucky. Unless you ruthlessly lighten your load and enforce a culture of speed and mobility, the insurgents will consistently outrun and out maneuver you. But in lightening your load, make sure you can always "reach back" to call for firepower or heavy support if needed. Also, remember to harden your CSS. The enemy will attack your weakest points. Most attacks on Coalition forces in Iraq in 2004 and 2005, outside preplanned combat actions like the two battles of Fallujah or Operation Iron Horse, were against CSS installations and convoys. You do the math. Ensure that your CSS assets are hardened, have communications, and are trained in combat operations. They may do more fighting than your rifle squads.

My advice to insurgents: Travel lighter. Nay, indeed, travel lightest.
