Because I want to expand what I do on this game, I want to get started on the Battlefield.

I know I have to create a Military Academy to get a Squad to go on the Battlefield, but I have no idea of good strategies/pets to bring/how the game even works there.

There don't seem to be any general Battlefield guides on the Player Guides forum, so I decided to ask here if anyone knows of any I may have missed. (Or maybe there's an official guide hidden on the site somewhere...)

Thanks for your time.

Hello there! 

We do infact have an "official" and current Tactics guide here: http://beastkeeper.com/tactics-faq  (Help > Tactics FAQ)

Not to many user-created ones because everyone has their own styles. There are a couple guides regarding certain moves like "hold the line" and such. 

Feel free to post your questions!

Thanks very much, Nightingale!
