I couldn't find this in the rules. Is it possible to have in an army 2 or more times the dame unit? Cause with the new Axis heros box we get 2 zombies hero so I wanted to have 2 unit of zombies with each their own hero. Can I do that?

"same" and "heroes" I mean

There are no restriction on the number of units you can have, just one of each hero though.

And i think you cannot field multiple comand squads;)

Only one command squad of each armor class.

Great! Now I can have my grotesque axis army! But because I like to read things for myself, where can I find this in the rules? About limitation of heroes and command squads and all? Is it in the revised edition? Thanks again.

From the Revised Core, Page 23:

A player can field more than one Command Squad unit at the same time, but in order to
do so, each unit must have a different armor class.

Only restrictions are on Command squads, heros, and "Rare Units" so far. I bring multiples of Beobachters/13 Foxtrot and the snipers all the time. I also often see people bring multiple copies of the Recon grenadiers because they are such a good value (probably too good a value IMO).

I field 2 squad of Recon Grenadier/Ranger with either army. They are a mainstay.

I agree, i also tend to field 2 to 4 observers and snipers on occassion.

This Saturday i used 3 Recon Grenadier squads in a 150 pt game. Now I want more LOL! Maybe 2 more boxes. Or another RCS plus extra recon squad.
