The prerequisite is that the Forbidden Guard Insect Race must be large enough in size.
Using the Titan Insect as a template, change the shape of the original forelimbs of the Titan Insect, forming them into shield-like structures by gathering a large amount of keratin.
Further thicken the front carapace, sacrificing mobility for absolute frontal defensive strength.
In combat, rely purely on mass and brute force shield strikes to inflict damage on the enemy.
To defend against the Mechanical Race's regular ground units, the defensive strength of these Forbidden Guard Insect Race should be enough to withstand a direct frontal shot from a centipede's Charge Cannon.
This is fairly solvable.
If defense is insufficient, supplement with Spiritual Energy.
The effect of the Insect Queen's Spiritual Energy is now sufficient to allow many Insect Race creatures to withstand many attacks from the Mechanical Race when specifically enhancing their own carapace defense.
