My friend used to play catachans but since the release of the new codex has been using the new rules. He wants to make a new jungle army and was thinking about using these doctrines:

Jungle fighters
I think it was hardened fighters?
and some restricted troop.

My question was are either types of rough riders, Xeno or normal, any good in jungle, and do Ogryns count as infantry for the puposes of drop troops and jungle fighters?
