The internet is a bad place.
Knowing that a percentage of the drop pods malfunction while landing,i'd say you would really have to be an idiot,insane or have supersized balls before even thinking about digging your own grave.
Imagine:You are all prepared,had all those long painfull hours of training,worked your ass off to get where you are,all pumped up and psyched to kick some butt.
You get in the drop pod,go down at dazzling speeds while being shot at by covie fire,get down,and feel your bones crack just before you die a very miserable death without even having a chance of defending yourself.
Sounds like insanity to me.
