Hi there, just noticed that you can give your trained units the juggernaut traits, (as long as you are playing as trogs ofcourse).
You go into the unit designer, and design a new unit, click on a "male", then click over to "Juggernaut", pick the traits you want, then click back to either "Female", or "Male" and see the traits persist, now equip your unit without changing traits, and you will have a unit with +40 hp, +100% damage, and maul... as one example...
Maul on trained units is really broken 
Sincerely
