>Only the most disciplined security squads can overcome their fear long enough to trigger the flame guns which can keep the worms at bay. Clearly you will have to tend carefully to the morale of the troops.
This is an interesting lesson in game design. The reason the mind worms fight using morale rather that conventional combat is because otherwise they wouldn't scale as your troops get stronger.
Supposing the mind worms had fixed conventional strength--on par with that of an ordinary early-game scout, for example. Then as soon as you get proton missiles or whatever, mind worms would no longer provide a challenge. But if you made mind worms challenging for the late game, then they'd be impossible in the early game. Hence the creation of a parallel combat strength scale, to better manage the mind worm difficulty curve.
