The Trooper serves as the vanguard of Republic might and firepower in SWTOR. However, it takes more than bravery, weapons, or armor to survive the perilous front lines of galactic combat, which is where the Trooper's companions come into play. During the course of his (or her) adventures, the Trooper, like every other class in SWTOR, will acquire five companions to accompany him and aid him in his journey. Each companion has their own unique role and has their own specific strengths and weaknesses. It is up to the player to decide on which companion to use with your Trooper depending upon the situation and your playstyle. To that end, Swtorhub.com has put together a complete guide to the Trooper's companions, including their crew skill bonuses, combat acumen, and likes and dislikes.
