The thruster pack, in wargames, is completely worthless. It barely moves you two steps forward and not much quicker than you can sprint it. This item desperately needs a re-tuning in the form of greater distance traveled.
(As a fun side note, go into a custom game with Player Traits set to Move Speed = 300% and gravity = 50%, and then hit the thruster pack... now there is some thrust! Unfortunately, unless you get a speed boost from an ordnance, you are handicapping yourself by having effectively no armor ability.)
