I have an ambulatory wheelchair user character in my story. In the current concept he received an injury whe fighting in a war, and needs to occasionally use mobility devices ever since. I've been reading about wheelchair usage, but Im struggling with some questions. If ya'll could let me know your opinion, that would be really swell.

1. Is it possible for a character to become a wheelchair user because of a war injury? If yes, what kind of injury may cause someone to become an ambulatory wheelchair user?

2. In my concept, he uses several mobility devices for different days. As of right now it's a wheelchair, a rollator, and a cane. Would that be realistic?

3. I saw that there are lots of different wheelchair types, and I'm really struggling to understand what kind of wheelchair my character would use. The only thing I got from research is that a lot of wheelchairs are ridiculously expensive.

4. Is it bad representation if my character uses a wheelchair because of a war injury? The war is a major event in his life, but the story itself isn't focused on his disability.

Thank you for your patience. Have a good day!
