[Aliens] How on earth were the Company planning on turning an alien creature that kills anything that moves on sight ( friend and foe ) into a biological weapon and for what purpose anyway, what war was Earth fighting that would need such weapons?

We know there were conflicts because of the existence of the Colonial Marines.  Some of those guys were serious veterans, with many combat missions under their belts.

As far as the utility of the Xenomorphs and Facehuggers -- well, they'd first need specimens in order to evaluate how they could effectively be exploited.  That's why they wanted to acquire them.

Some things probably jumped out to the W-Y board just based on the story Ripley told.  Weapons manufacturers would certainly be interested in molecular acid that can burn through steel.  A species that can paralyze its prey while impregnating it probably also manufactures pretty potent pharmacological substances.
