IL child support-military pension

I have posted a question and received an answer...I wasnt sure how to post again to elaborate on the answer so I am reposting....
When I retire from USAF, I will receive a pension.
I will, of course, still need to take a civilian job because the pension is not nearly enough to live on. I will also assume the civilian job will be less of a salary than current military pay.
In this case, Will IL courts consider my pension as net income if my ex-wife or I decide to ask for child support modification?
