Can I join the Army Reserves or National Guard if I am currently collecting compensation from the VA?

I believe it depends on your medical condition and the percentage of disability you are collecting.

This a very fact specific question. The simple answer is yes as long as you don't have a condition or take meds that make you non-deployable. As stated by others, you can't receive drill pay and VA disability concurrently. once a year you have to report the number of days you were paid for by the military to the VA and ellect if you want to loose those days in drill pay or VA disability. Simple math.

You can. Go to your local recruiting station

Great quesiton and conversation, I have been very enlighten.

They will give you an option after the new year for the commander to sign, then depending on how many days you attended drill they will stop you compensation for that may days.. example you drill 56 days total all year then you will not get compensation taken for 2 months.. they will give you plenty of notice before..

The answer is that it depends. The chances are that you might not be able to pass MEPS and AR 40-501 requirements for enlistment/commissioning in the US Military if you are disabled enough to qualify for compensation.

I thought about your question for a few seconds and just shook my head. I thank you for your prior service, which was interrupted by an injury of some kind, and I am happy you got an Honorable Discharge so you can collect VA compensation.
However, Ask yourself this! Will my disability interfere with the safety of my unit or completion of their mission. If it would interfere with their safety or ability to complete the mission successfully, then I would have to say no don't attempt to reenter the Army.
You are a veteran, you served, now accept what has happened and find another way to enjoy the camaraderie you enjoyed before. Veterans Associations, events on local posts, etc. God bless and I salute you for your desire to serve our great country.

I just feel bad for our Korean War veterans, Vietnam-era veterans, Desert Storm/Desert Shield veterans, and pre-9-11 vets who have been shafted by the VA when trying to do their initial and follow-on VA claims.  I’m truly thankful that the VA claim system has improved during my era, and I would never truly understand the frustration that some of our previous veterans have gone through.  Without their lobbying of Congress to fix the system, I would have never been in this position.  I’m truly grateful to all those past veterans who have addressed these issues. 

I think that might tie in with having your cake and eating it too. Doesn't the disability pay
identify you as someone unable to perform normal duties. How would you be able to join the Reserves or National Guard if you're been identified as disabled?

FWIW, i went in the Marines while collecting VA compensation from Army service. of course, the compensation stopped while i was active and i had to be re-evaluated when i left the Corps.
