A resposta curta é que o filme não reflete os eventos da vida real neste caso. Ao invés de morrer logo após o incidente, como descrito pelo filme, Ryan Job foi demitido da Marinha, se casou e faleceu mais de dois anos depois devido a complicações da cirurgia de reconstrução facial. Isso é mencionado em vários artigos comparando o filme ao livro / vida real.

Did Ryan "Biggles" Job only survive for a short while after being blinded by a bullet?
No. In the movie, Ryan "Biggles" Job (Jake McDorman) is blinded by Syrian sniper Mustafa. He survives for a short period of time and proposes to his girlfriend while in the hospital. Kyle visits him shortly before leaving for his fourth tour and learns of Ryan's death just after he arrives back in Iraq.
In real life, Ryan was blinded in battle in 2006 when an enemy sniper's bullet struck his rifle, sending pieces of the shattered weapon through his face. He survived much longer than he does in the movie. He was discharged from the military, got married, attended college, got a job, climbed Mount Rainier and Mount Hood, etc. He died in 2009 from complications after going back for more facial reconstructive surgery while his wife was pregnant with their first child

In the movie, Ryan Job (or “Biggles,” played by Jake McDorman) is shot in the head and blinded by Syrian sniper Mustafa but survives long enough to propose to his girlfriend. He dies soon after, and that death defines Kyle’s fourth tour in Iraq and spurs him to seek revenge against Mustafa. In reality, according to Kyle’s memoir, the Navy discharged Biggles from service following his injury. The ex-SEAL attended college, began a career, and got married before dying following facial reconstruction surgery while his wife was pregnant with their first child.
