Can I get somebody to confirm this? I was told (after I got a rear charge with 3 terradons) that I did not get the +2 because they were flying calvary which made them skirmishers.
I'm fairly certain they do get the +2 bonus for a rear charge, I'm not certain whether they negate the enemies ranks. Don't have my rulebook with me at the moment... should say under Flying Cavalry though.
flying cavlary = flying unit = skirmisher skirmishers get the bonus but don't negate ranks per BRB skirmshers rule. search those few pages and you will find it to be true
I can also confirm this to be true. In addition, in the rare event that you should have something like 2 units of 2 terradons charging the enemy in the rear, you do NOT get the +2 bonus (though they are US8 in total). The bonus can only be generated by a single unit with US5.
