stances permit will precede a call of this nature, but no specific period of warning can be predetermined. The nature of an emergency, the urgency for troops or officers of a particular class, and the theater of operations must be expected to introduce variations into any predetermined plan. 47. The maximum obligation for active duty in time of peace is 15 days in a calendar year. It will, in general, be impracticable to require this maximum. When officers are to be called for a 15 day training period, they will be given as much advance notice as practicable, and any officer upon whom such a call to duty would work a hardship may be excused from attendance for that call. Specially selected officers will be called to active duty from time to time for the following duties: (a) As additional members of the War Department General Staff; (b) To attend the various service schools; (c) For duty with organizations of the Regular Army or Organized Re serves; (d) As instructors at training camps or schools; (e) For consultation, duty on courts-martial or boards, or other duties for which specially qualified. 48. No active duty of the above classes will be required without the consent of the officers concerned. In addition to the consent of the officers, selection will be based upon special fitness and recommendations, and with the view of securing a uniform distribution of specially trained officers. throughout the Army. As such active duty is dependent upon appropriations made, facilities available, and other varying factors, it must be controlled by policies formulated and announced from time to time. 49. In justice to the Government and to individuals, it is essential that the physical fitness of reserve officers be determined when they are placed on active duty. While minor physical defects may be waived if the nature of the contemplated duty permits, it is essential that future expense to the Government and interference with military efficiency be avoided, by not placing or retaining on active duty any officer who may become a burden through disability aggravated by service. Any officer, upon reporting for active duty, found disqualified for the performance of any duty will be immediately relieved and returned to inactive status. 50. When on active duty reserve officers are subject to the Articles of War and to assignment to any duty, and receive the pay and allowances provided by law for officers of like grade of the Regular Army. Reserve officers are not entitled to retirement or retired pay, their compensation in the event of disability being otherwise provided for by law. SEPARATION. (For details see Sec. XIX.) 51. The separation of a reserve officer from the service may be either of his own volition or for cause. In time of peace resignations of reserve officers will, in general, be accepted when tendered for any good reason. The period of appointment as a reserve officer is five years. At any time prior to the expiration of the five-year period reserve officers may be discharged for cause. Such discharges will be preceded by suitable investigations by boards of officers, the membership of which will, when practicable, include reserve officers. 52. In time of war reserve officers will be subject to the same conditions as to separation from the service as are all other officers of the Army, except that only officers of the Regular Army are entitled to retirement. Any reserve officer whose appointment is in effect at the outbreak of war, or whose appointment is made in time of war, is entitled to his discharge within six months of the termination of the war. 53.
