The flow is nice for an introduction but leaves me a bit confused about the world and the MC. In this chapter, it is mentioned that the MC joined the military at 18, but since I do not recall how old he is it is difficult for me to know how long he was in the military.
Despite this, the flow is still nice. It does a nice job world building and leaves me interested by how things work. It does get wordy within the dialogue to the point where I forgot someone was talking, with this I am referring to Mrs. Watts.
You do a great job of making me experience this at the same time as the MC. The MC doesn't need the world explained to him, but don't forget that your reader will. While we are often smarter than writers think it is a challenge for us to know the world if you do not tell us. There are ways to go around this, you can make chapters that are newspapers or chapters that are not in the MC's point of view.
