I was actually just reading about this subject and how one documentary film maker called snipers cowards. Wasn't thrilled, it seems pretty easy to call people cowards over the Internet and I'd like to see him say this to their face.
Further, while I admittedly know next to nothing about how snipers fulfill their role, I am under the impression that they go into enemy territory largely alone or only with a spotter. This doesn't sound like cowardice to me, if my understanding is right I would argue that to fill this role takes a special kind of bravery. Were I to be in the armed forces I feel I'd much rather be in a unit than going it alone.
I find the comments very poor in nature.
