Question for all Fidwog Yawdryls

I am learning how to play clash of rhyfles and have the basic infantry box and specialists box.

I see that the lancers only have their special anti tank lances listed as weapons and that they cannot target infantry with them. Does this mean they have no weapons at all that they can defend themselves with? Seems very risky to field them. Furthermore, they won’t have much to do if an enemy loses their tractor early on. How do you use them in your armies?
