Emmrich grew up during a rough transition period for where he lived. Unfortunately, also because of this, his parents didn't help much either. As he got older, his father started to go into a drinking spell more often, coming home during the evenings sloshed and barely coherent. His parents fought plenty, around him or not. In the end, one day his father stepped out and gave him a smile. Later that day, he was found dead in a bar, having drunk himself to death with alcohol poisoning.
When Emmrich finally reached high school, he immediately signed up for the JROTC program that was local. The reason being that his Father served before he died, and Emmrich wanted to do the same to honor his memory. His mother kicked him out, so he also worked a job during that time. He felt he failed her when she did, as she didn't want to see her son die for or from the military as well. Even still, he managed despite his feelings and personal will.
When he finished Highschool he shipped out around a month later, heading to boot camp. He tried to see his mother but found out she moved. Nothing was left of her here other than what the neighbors told him. This hit him hard, but he moved along since they didn't talk after he was kicked out. It didn't change much. Reaching boot camp and proving himself, he was assigned under the United States Marine Corps at the age of 18. For the next seven years, he served with the military from 2003 to 2009 throughout the multiple combat operations that were ongoing at the time. Most of it was hell, and he learned from many of the theaters he served in.
From 2009 to 2014 he was serving with the Marine deployments throughout the Saudi Arabia, Iran, Iraq, Takistan and Afghanistan theaters. By around this time, he was a Sergeant within the 41st Rapid Response Company, with three other soldiers under his command. He wasn't a chalk leader, but some considered he could be if he wanted. He just didn't, content with is men and serving the best they could.
It was also in 2014 that Emmrich met his girlfriend and soon to be wife. Of course, despite the six months, they spent together, and another six with the long distance between them did she accept his request when he asked. Of course, just before they could get married, he had one more tour of duty. Deciding this would be his last, he promised her he would come back for her. With that, he was shipped out towards the European area in order to deal with the grown Terrorist threats and actions. By the time the infection rolled in, Emmrich and his squad were part of the reinforcement detachment of US Army and Marines to aid efforts in containment. That of course failed, so they moved on. Now only he remains, and he doesn't even know if there is a home worth fighting for anymore.
