Anti-war? They are non-clan and need the extra def as a detterrant? They just prefer to be defensive to dodge hits while they hit thier Inactives? It's just them being defensive as a build choice? It all depends..
There actually is a very smart way to use defensive troop buildings when at war. Just requires a reverse in common thinking.
I naturally like defense rather than offence so i choose a def build its fun to see ppl burn their troops on u
