I’m a 23 year old male that got out of the army on a medical discharge. I want to burn some fat, but I cannot do much of any workout that requires use of my legs. Can I do high intensity weight lifting to lose weight?
yes. it will raise your metabolism and the repairing of the muscle causes you to burn fat. the bigger the muscle group being worked, the more this happens.

Repairing muscle doesn't directly use fats. Instead, your body's resting metabolism will increase due to an increase in lean (muscle) tissue, which requires more energy for sustainment than adipose (fat) tissue. Energy sources in this case, and in the case of energy spent rebuilding muscle tissue, doesn't come specifically from fats, but from all three macro nutrients.
However, if you are still taking in more calories than you are burning in a given day, your body is still going to need a place to store the extra energy (ie. fat tissue).
In essence, if you're going to try and lose weight through resistance training alone, you need to develop and adhere to a healthy diet (getting all your food groups) while maintaining a caloric deficit. If you're not sure how to find out how many calories you are burning, do a google search for resting metabolism calculator, as well as a search for energy expenditure during exercise. You should be able to add those up to find your baseline caloric expenditure and you can determine your overall caloric intake from that.
Also remember that you don't want your caloric deficit to be greater than 400-500 calories, or else you may force your body into a "starvation mode" where it will begin to horde calories as fats because it is unsure of it's next meal.
In the end though, it's still easier to create a caloric deficit and burn fats directly though cardio, so I would try getting in as much as you can. In your case, a hand cycle or pool work would probably be your best bet if you have access to them.
Best of luck!
