If you are disabled, you are entitled to disability compensation in puportion to the level of your disability. For other benefits, you would need to contact your local AMVETS representative or the VA.
If you regain your sanity, YES
You could be discharged for arthritis. If the medical condition prevents you from being effective, you can receive a medical discharge. If it is bad enough, you could receive disability pay.
It depends on what type of Governmental help you are referring to and whether the Marine has received an honorable discharge in the past, previous to his Dishonorable Discharge. If a Marine in his or her 1st enlistment receives a DD then the Marine will lose many benefits. If however the Marine served one enlistment and received an Honorable Discharge and then reenlists he will be entitled to all benefits from that first enlistment. But you still need to speak to a Veterans Affairs Representative for details.
No.
Rank is not normally reduced when discharged. If they are discharge dishonorably, they may have a reduction in rank as part of the punishment. Normally you keep the rank you earned and retirement benefits are based on the highest rank obtained.
Yes it is possible.
Yes Randy Orton was a Marine however he was dishonorably discharged after going AWOL.
Yes there certainly are regulations. If you are a member of the reserves, you may wear the uniform on appropriate occasions. If you have retired, or been discharged on medical disability, you are entitled to wear it. Otherwise, you are no longer authorized.
Most likely. The Marine Corps does not allow any sort of disorder which would greatly affect a Marine's capability to fulfill his/her duties.
Nope. You are considered a recruit, aka a Boot. You are not considered a Marine until you earn your E.G.A. You will be taken care of with medical treatment if you get hert while at bootcamp and you get paid the pay grade you go in as. But G.I. bills wont include to your care until you are a Marine.
You will get paid up to the date of discharge. After you have been discharged (just like being fired), you don't get paid.
The "benefits" of being a naval marine are none. In fact all Marines are "Naval" due to the fact that the Marine Corps is a segment of the Departmet o The U.S.Navy. WRONG
