I few years ago I had to give a 12 minute presentation on the subject of my choice for a promotion course, I chose How to Survive a Zombie Invasion! They all sniggered at the time but I bet they'll be wishing they kept my handout when they see this!
I grew up playing the Resident Evil games, and don't worry about zombies, we all know you aim for the head according to Jill Valentine in the Resident Evil film
Duhhh anyway can survive for 12 mins, especially if your non-inf (run!!!), don't issue non-inf front ceramics anyway they don't need it! only need the back one thats where they will catch the most rounds
