to be honest, id rather go for either the marines or even an odst regiment, anyday, sure id be human and not some cybernetically and surgically enhanced killing machine, but hey for those of you who have completed halo 3, you know that all the master chief got as thanks was to be put back into cryo inside the debris of a unsc frigate millions of light years from the nearest planet, thanks but no thanks!
ill stick to being meat for the grinded, at least when i get ripped in half by a brute it will be on good ol earth! ;-)
