you might want to watch strike witches last, because it's pretty much the greatest fanservice show ever made.
The fanservice is excellent, but so is that action and you can tell the creators had a lot of fun with the show since there are so many subtle wwII and wwI references. For example, Billy Bishop was known to be a great shooter but a horrible pilot, he still managed to get 72 odd kills, but it was all due to his ability to shoot rather than to fly. This knowledge is pretty much the basis for the plot of the episode where the girl based off of billy bishop can't fly and shoot at the same time, but when they do focus 100% on shooting they're the farthest shooting member of the squadron and she serves as the squadrons sniper.
Or the aircraft carrier in one of the episodes is hit in the exact same location where it was hit in the battle for midway.
