Cobra Trilogy

The colony world Adirondack and Silvern fell to the Troft forces almost without a struggle. Outnumbered and on the defensive, Earth made a desperate decision. It would attack the aliens not from space, but on the ground - with forces the Trofts did not even suspect. Thus were created the cobras, a guerrilla force whose weapons were surgically implanted, invisible to the unsuspecting eye, yet undeniably deadly.
