Okay that's what I was guessing.
As for armour, I feel like the 2005 rules use of Structure Levels was an excellent way of working against having weak guns not have a good chance at being effective against stronger units, but combined fire let the weak units have a fighting chance. With this new armour thing, that problem is eliminated but it now brings into question the essential fairness of an inherently unfair force deployment.
For example, if I use my Spider Tank and say it is armoured, then if my opppnent has only a small squad of police officers with handguns, my tank can just roll into town and level the place without any fear of being harmed. Obviously that is how it would happen IRL unless the officers got the hatch open, but I worry about anoraks making some really crappy units be armoured even though they totally suck. But I guess it is hard to write a rule to protect against rules lawyers.
