Battle It Out by Reese Knightley

Battle It Out on the way to love.
Battle it Out Blurb
Master Sergeant Zane Gannon loves nothing more than being a part of his Special Forces unit and kicking ass, but above everything, he values his friendship with Isaac. Sure, they argue and snipe at each other, but it’s all in good fun. Until it isn’t. Now, Isaac is pulling away and something Zane has buried for two decades is resurfacing.
Staff Sergeant Isaac Thorne has loved Zane Gannon from a distance for three years, and he was doing just fine concealing this fact until the colonel decided to pair them together a year ago. Now, it’s becoming increasingly difficult to hide his feelings, so he takes to avoiding Zane. So what? The man is infuriating and straight, and lately, he’s acting very strange.
The fire ignites between Zane and Isaac when things come to a boiling point on a mission and the locker room gets heated. Infinity takes on several new recruits. BFFs are not who they seem, and a mission goes horribly wrong when a group of homegrown terrorists rear their ugly heads.
Hold onto your helmets for a bumpy ride as these two soldiers battle it out.
