Keegan and Hesh

Hash is a tall man with a strong, athletic, and muscular build. He has short dark brown hair and pale greenish eyes. He has a distinctive tattoo of two stars on his right arm.
Most often, Hash wears modern American tactical camouflage, a bulletproof vest with magazine pouches, and a radio on his shoulder.
After officially joining the Ghosts special forces unit, Hash, like the rest of the squad, begins wearing a signature balaclava or half-mask with a recognizable design of a human skull.
An extremely serious fighter. During missions, he is cool, collected, and almost never displays personal emotions, remaining focused on the combat mission.
He possesses strong leadership qualities and a keen intellect. Hash is very attached to his younger brother, Logan, and their German Shepherd, Riley. He always tries to look out for his brother on the battlefield and takes on the role of commander after the tragic events involving their father.
The loss of his loved ones makes him harsher and more radical in his methods. His main driving force in the second half of the story is his desire to take revenge on Gabriel Roark for betraying him and destroying their family.
