Gather as many non zombie people you can find and arm yourselves with bats, clubs, firearms prefered shotguns, and go zombie hunting. The National Zombie Institute has established the following guidelines to the OFFENSE tactic.
1. Never use chainsaws they we eventually do more harm than good.
2. Do not allow children no matter how dire the need, wield a firearm see rule 1.
3. Stay orderly and dispatch zombies in a repeat manner, trying to show off or going into a frenzy will only cause ones demise.
4. If someone is scrathced bitten, or answers your question of "Are you Ok?" with "yea.. yea.. im fine." That person needs to be imediatley eliminated, that means killed. The NZI reports that 68% of infections are inflicted by "friendly persons that have turned into zombies.".
5. Zombie killing group should be 2:1 ratio against zombies.
Offense is an effective zombie proofing technique, just remeber SAFETY FIRST.
