What's gonna get in that LAV? Plus I think they have in excess of 100 gallons of diesel onboard...
and that will run out eventually.
it will run out faster if you are on the gas pedal trying to get traction on slimy zombie guts.
that vehicle isn't the most fuel efficient i'm sure.
You can survive
or
You can take the fight to the enemy
I think with zombies a doolittle aproach would be required in order to save your sanity
you would have to be very careful in your approach to taking otu the zombies. i would thank that guerrilla warfare would be best agaisnt them. small attacks to whittle them down so as to not get overwhelmed. that would take a VERY long time to get rid of all the zombies given their rate of reproduction. now there would be a point when there simply aren't any more humans to infect so the rate would slow and eventually stop. however, that is a shit-ton of zombies. to get rid of them we are talking a scorched earth attack. plus, assuming you and the twins arent' the only survivors, getting in touch with others to coordinate a large scale attack will be dam near impossible. the zombies won't die, just rot away.until the brain is totally decomposed they will still be a danger. that could take longer than you can keep on the run.
i still prefer to stay light and mobile with an out of the way easily protected base of operations.
