I Need Good Military Sci-fi

I read and fell in love with Starship Troopers

I followed that up with Armor and loved the beginning and the end. IYKYK

Old Man's War was great and so we're a few of the sequels, but I feel like they're losing the thread and I need a break

I've read most of the Ender's Game books and enjoyed them.

I've seen recommendations for The Forever War, but it sounds a little too bleak.

What I'm really looking for is dudes in power armor killing aliens. I don't need something that's going to make me think. Just good old fashioned machismo and laser guns.
