I need some help

Hi guys!
I´m in search of a manga, and really hope someone might know which one it can be.
It´s been years since I read it, and think there was only 1 or 2 chapters then, so I don´t know much. But it was a bl, and if I remember correctly it was about a group of guys, I think they were soldiers. And I´m pretty sure they might have been some kind of experiment, with animal dna to make them stronger or something.
I think the story begins with them out on a mission, or returning back to their base from one.
And that`s all I remember T__T apart from it seeming to be really interesting, and with beautiful art.
Since I lost track of it I really hope someone can help.
