I would say, it depends on the commander.
IF he can not utilize his troopers abilities to bring the enemy to their knees, then it's kind of a waste of time.
However, they are really good for tornaments. Still armed with their 5+ armor, it isnt much, but it's better than a 6+.
Also, another good thing is, they have advantages from all boards. Not just jungle, in game terms, all forms of terrain can make them superior in cover, almost like terminators. They provide tons of anti infantry weaponry, but little anti tank gunners.
Over all, they are good, but only if you use them right.
