I'm writing a sci-fi war/spy novel. I'm done writing the prior event, prologue and first part of the novel, which pretty much cover the 'spy' part. Now I'm at the point where I should start adding the 'war' part, but how should I handle it? The 'war' part follows the adventures of a young nurse. I pretty much have a general idea on how I should manage this section, but the scenes are kinda all jumbled up in my mind, without any kind of connection whatsoever. I though I would start off by describing her journey to the war, from when she leaves the naval school of medicine on Earth to when she reaches a hospital behind the front lines on a frontier planet. The problem is, how do I describe it? And which means of transport should I make her use? Civilian trains/airplanes/vessels (starship) or military ones? What would a real navy officer use to reach the combat zone?
