Looking to find a sci fi trilogy i read years ago but can't remember title, author or even character names.
The main character starts off as being a soldier on a distant desert planet being whipped for some crime. As the story goes on it says he lost an arm fighting against a creature. I think it might be as he's being punished the creatures attacked his camp?
Later in the trilogy he's fighting for an empire as a sargaent where the enemy has leaders that have a higher amount of metal coils on their head (I'm thinking of dreadlocks?) or similar depending on their rank.
Hoping someone can help me out!
