Otto Weber was born in Dortmund the 30th of August of 1979. He was born into a pretty wealthy family and received good education and achieved good grades. Otto was obsessed with chemistry and everything military. In his teenage years he discovered SEK, a well trained, tier one unit dedicated to hostage rescue, high risk warrants and counter terrorism. He was particularly interested in the Bio-Chemical warfere unit and dedicated the next years of his life to make the cut for SEK. He went to collage and got a masters degree in Biology and Chemestry all while training to become a Chemical, Biological, Radioactive and Nuclear Threat Management Operator (CBRN-TMO). Out of 25 men that graduated in his class he was in the top 3 in almost every aspect of training school. After making the cut for SEK's CBRN unit he was deployed to various cities in germany for various missions and participated in 2 hostage rescue missions (both successful), 1 acid attack in which he recieved a medal for his outstanding performance in the defusal of the attack. He was later involved in an active shooter situation in which he got shot in the left knee and upper thigh while helping an assault team (as there was no active CBRN threat he volunteered as an assault operator as he was an experienced shooter) After 10 years and 17 successful missions in SEK he retired due to his injury. 3 years later he was fully recovered but had surpassed the age to re-join the main SEK CTU unit. Instead he joined a german para-military outfit attached to the United Nations, this outfit consisted in units trained in Radiological and Bio-Chemical control and fighting and was sent to North Africa as part of the GWOT program (Global War On Terror) and lived there for 8 months. On his back to germany he was asked to join a UN Supprt Group that was to be sent to chernarus after some kind of biological disaster. He was given little to no information on what this threat was but he agreed to go anyways. His superiors had told him it'd be a simple humanitarian mission. When his group got there they were attached to a unit of U.S. Marines and was ordered to hold an important coastal city named Elektrogorsk. He was there for two full days until the CP in the city was overran. At some point in the night of the 27th of July the city was in total chaos, civilans ran everywhere trying to get to shelter as the worried Marines has started rigging streets with plastic explosives in order to stop the infected. By the morning of the next day the city had fallen and Otto had been separated from the rest of his detachment. When he woke up he walked around of what was left and couldn't find anything alive.
