In your situation, the military has no effect on the sale of the home.
Most likely, any gain will be fully taxable. However, there are a few certain circumstances that MIGHT change things. Why are you moving? Is it is just personal choice, or is there some specific 'reason' for moving (and if there is a 'reason', please give as much detail as possible about that reason)? For example, some people may move due to a new job in another city (I know you said you are retired, so that may not apply, but I'm just giving an example of a 'reason' why a person may move).
