I have noticed when playing Kraxis, if you form a fortified defensive line, the enemy melee units will not advance. What happens is they all pass their turns. Long Range Units on the other hand will fire. If they don't have any long range units, the melee units simply stand still and become cannon fodder for my long range units.

Here is a view of my defensive line. Keep in mind that this screenshot was taken after several rounds of play. The enemy melee units do not advance as long as my fortified line remains stationary.

Here is a view the moment I break my fortified defensive line. Notice the melee unit starts to advance.
