what is the easiest and fastest way to get out of the marine corps…

Here is some examples...the text is from the Army reg but the Marine Corps is virtually the same

Families of servicemembers frequently experience some financial hardship or psychological strain resulting from the disruptions of family life associated with military duty. To be granted discharge, however, a member must be experiencing more extraordinary conditions. Grounds for hardship or dependency discharge do "not necessarily exist solely because of altered present or expected income, family separation, or other inconveniences normally incident to Military Service."

The basic standards for both hardship and dependency discharges are the same:

"The hardship or dependency is not temporary [usually interpreted as lasting more than a year];

"Conditions have arisen or have been aggravated to an excessive degree since entry into the Service, and the member has made every reasonable effort to remedy the situation;

"The administrative separation will eliminate or materially alleviate the condition; and W "There are no other means of alleviation reasonably available."

A discharge application cannot be denied merely because the person is in debt to the military or government or because the person's services are needed by the military

If the hardship or dependency is of short duration, the member can apply for "humanitarian reassignment" (or "compassionate reassignment" in the Army) to a duty station closer to home: Criteria:

The problem is temporary and is expected to be resolved within one year; The problem cannot be resolved through the use of leave, correspondence, power of attorney, or the help of family members or other parties; The problem neither existed nor was foreseen at the time of latest entry on active duty;

If the problem involves the health and welfare of a family member, in the Army and Navy the family member must meet their definition of "immediate family." (However, parents-in-law may also be considered.); A vacancy must exist at the requested duty station.

The Actual Army Regulation on Harship Discharge says:

6-2. Dependency or hardship

Upon the request of a Soldier and approval of the separation authority, separation may be directed when it is considered that continued membership and service on AD, full-time National Guard duty (FTNGD), or ADT, would result in genuine dependency or undue hardship.

a. Criteria for separation. Separation may be approved when all of the following circumstances exist:

(1) The hardship or dependency is not temporary;

(2) Conditions have arisen or have been aggravated to an excessive degree since entry in the Army, and the Soldier has made every reasonable effort to remedy the situation;

(3) The administrative separation will eliminate or materially alleviate the condition; and

(4) There are no other means of alleviation reasonably available.

b. Limitation of criteria for separation. The following circumstances do not justify separation because of dependency or hardship. However, the existence of these circumstances does not preclude separation because of dependency or hardship provided the application meets the criteria in aabove.

(1) Normal pregnancy of a Soldier's wife is not a condition for which his separation is justified.

(2) Undue hardship does not necessarily exist solely because of altered income, separation from family, or the inconvenience normally incident to military service.

c. Conditions of dependency or hardship.

(1) Dependency. Dependency exists when, because of death or disability of a member of a Soldier's family, other members of his or her family become principally dependent on him or her for care or support to the extent that continued membership and service on AD, FTNGD, or ADT, would result in undue hardship.

Consider getting help in putting your ducks in order, and pulling together the documents and written statements you will need. The Army Regs say:

Application for separation. A Soldier must submit a written application to be separated because of dependency or hardship. A request for separation will be submitted as follows:

(1) An ARNGUS Soldier, or USAR Soldier assigned to a TPU or IMA duty position, must submit a written application to the unit commander who will immediately forward it with recommendations and Soldier's records through channels to the separation authority (para 1-10) for final action.

(2) A Soldier assigned to the IRR, Standby Reserve, or Retired Reserve, must submit a written application to the Commander, HRC-St. Louis, ATTN: AHRC-PAR,XXXXX St. Louis, MONNN-NN-NNNN The Chief, Regional Personnel Actions Division, will immediately forward it with recommendations and Soldier's records through the Director, Personnel Actions and Services Directorate, and Director, Enlisted Personnel Management Directorate, to the Commander, HRC-St. Louis (para 1-10b(1)) for final action.

e. Evidence required. The evidence required for dependency or hardship separation will normally be in affidavit form. The evidence must substantiate dependency or hardship conditions on which the application for separation is based.

(1) The evidence will include affidavits or statements submitted by or in behalf of the Soldier's dependents and by at least two disinterested persons or agencies having firsthand knowledge of the circumstances. If dependency or hardship is the result of disability of a member of the individual's family, a physician's certificate should be furnished showing specifically when such disability occurred, the nature thereof, and prognosis for recovery. There also will be furnished the names, ages, occupations, home addresses, and monthly incomes of other members of the applicant's family. The affidavits of disinterested individuals and agencies should include reasons within their knowledge that these members of the family can or cannot aid in the financial or physical care of the dependents concerned for the period the Soldier is to continue membership or is ordered to AD, FTNGD, or ADT. When the basis for the application is the death of a member of the Soldier's family, a death certificate or other proof of death should be furnished.

(2) If the basis for the application is parenthood of either a sole parent or a married oldier, the supporting evidence will be in affidavit form and will substantiate the applicant's claim that unexpected circumstances or circumstances beyond his or her control have occurred. These circumstances prevent fulfillment of military obligations without resultant neglect of the child. Affidavits from the Soldier's immediate commander and officer who is the job supervisor will be considered sufficient. Evidence in (1) above is not required for these applications; however, sole parenthood resulting from divorce or legal separation will be substantiated by a judicial decree or court order awarding child custody to the Soldier.

f. Procedures. On receipt of a written application with required supporting evidence, the separation authority will-

(1) Consider carefully the facts on which the request is based.

(2) Obtain any other information that may be necessary to determine the validity of the request.

(3) Take final action to approve or disapprove the application.
