Ungors are the lowest class in Beastman society, brutalised (an often eaten) by the larger Gors. Nevertheless, they are used in scouting and raiding roles in the army. They form the skirmisher elements (though not very good ones) and provide some (though poor) bow units.
So why bother taking them? They are useful in an ambushing role to take out enemy warmachines from behind, as well as screening the main Gor warrior units.
Even better, I got to put them into action today in a Warhammer game against High Elves. They did very well (for Ungors) but I did like seeing this:
which reminded me of this :-)
This unit takes my Beastman Army past 200 foot figures - most painted in the past year during AHPCs X and XI
