Suggestions and Questions.

Ok I've watched alot of anime recently and I've not seen alot of good war animes....Besides beserker I don't really know many. So if there are any good war anime idk if it has mecha magic demons or whatnot just alot of balls to the wall ass kickin goodness.

Sengoku Basara(armies are just cannon fodder)
Library war(well no so much so realistic war and not action packed but pretty nice)

I guess you can count in any gundam series as they usually have a war in it.

Ahahahaha samurai warriors lol
