hi speed, consider IC layout design. It is possible to do it with one really bummed out shoulder from a wheelchair.
Here's what is involved: Sitting, looking at a computer monitor, using a keyboard with no particularly fantastic skill, remembering where to find important information you need once every year or so, and moving a computer mouse. The job may sound boring from that description, but all the work is mental. You see the input, which is an electronic schematic diagram, and you use the keyboard and the mouse, mostly the mouse, to create the output, which is a picture of how the circuit will look as patterns on the silicon chip. You draw "pretty pictures" with the software, as fast as possible, and run some software programs against it to check and see that you did it right. The salary range is similar to engineers. Do a google search, look for a community college that teaches the basics, and try persistently to get into a job. Many IC companies would bend over backwards to put a disabled veteran to productive use.
If you excelled in the military system, you are well prepared for it.
