Have a son who is stationed at Ft Bliss, TX. He has been in the Army a couple of years now,he has informed us he is being discharged on a Chapter 10 due to "knee problems".Question is what is a Chapter 10?. Just a liitle insight please. Thanks!!

Are you sure he said Chapter 10? Because that's an involuntary discharge in lieu of a court martial proceeding. Here's part of AR 635-200 which covers enlisted separations:

Chapter 10
Discharge in Lieu of Trial by Court-Martial
10–1. General
a. A soldier who has committed an offense or offenses, the punishment for which under the UCMJ and the Manual
for Courts-Martial, 2002 (MCM 2002), includes a bad conduct or dishonorable discharge, may submit a request for
discharge in lieu of trial by court-martial.
(1) The provisions of RCM 1003(d), MCM 2002 do not apply to requests for discharge per this chapter unless the
case has been referred to a court-martial authorized to adjudge a punitive discharge.
(2) The discharge request may be submitted after court-martial charges are preferred against the soldier or, where
required, after referral, until final action by the court-martial convening authority.
(3) A soldier who is under a suspended sentence of a punitive discharge may likewise submit a request for discharge
in lieu of trial by court-martial.
b. The request for discharge in lieu of trial by court-martial does not prevent or suspend disciplinary proceedings.
Whether proceedings will be held in abeyance pending final action on a discharge request per this chapter is a matter to
be determined by the commander exercising general court-martial jurisdiction over the individual concerned.
c. If disciplinary proceedings are not held in abeyance, the general court-martial convening authority may approve
the soldier’s request for discharge in lieu of trial by court-martial after the soldier has been tried. In this event, the
officer who convened the court in his/her action on the case should not approve any punitive discharge adjudged. The
officer should approve only so much of any adjudged sentence to confinement at hard labor or hard labor without
confinement as has been served at the time of the action.
