Opinion by
Judge MacPhail,The Petitioners above-named1 appeal from the orders of the State Civil Service Commission (Commission) which denied each Petitioner veterans’ preference points resulting in their non-selection for appointment to the position of administrative law judge with the Pennsylvania Public Utility Commission. We reverse.
At issue is the question of whether training time and service in the Pennsylvania National Guard and/or the U.S. Army Reserve entitle the participant to the benefits provided by Chapter 71 of the Military Code (Code), 51 Pa. C. S. §§7101-7109.
It appears from the Commission’s findings of fact that Petitioner Ilerskovitz served in the Pennsylvania National Guard from January 3, 1970 to January 2, 1976. He was on active duty for training purposes from April 22, 1970 to October 18, 1970. He was honorably discharged on January 2, 1976.
Petitioner Cocheres, while attending college, served in the Reserve Officers Training Corps from Septem*430ber, 1965 to May 24, 1969. He entered the U.S. Army Reserve in September, 1967 and spent six weeks at a summer training camp at Indiantown Gap Military Reservation during the summer of 1968. He was appointed a 2nd Lieutenant in the U.S. Army Reserve on May 25, 1969. From September 22, 1972 to November 28, 1972 the Petitioner underwent basic training at Fort Gordon, Georgia. On May 24, 1977, he was honorably discharged from the U.S. Army.
Petitioner Strohecker, while attending college, served in the Reserve Officers Training Corps for 4 years. He participated for three months in an armor officer basic training course in 1971 and upon completion thereof he was released to the U.S. Army Reserve where he served from January, 1972 through September, 1975. He has been a member of the Pennsylvania Army National Guard since October, 1976.2
In arriving at its decisions denying the Petitioners veterans’ preference, the Commission interpreted the language in Section 7101 of the Code, 51 Pa. C. S. §7101, to mean that only those persons who were engaged in full-time active duty other than active duty for training, would qualify for the benefits provided by the Code.
Section 7104 of the Code, 51 Pa. C. S. §7104, provides that a “soldier” who possesses the requisite qualifications under the Code, is entitled to its benefits. Section 7101, 51 Pa. C. S. §7101, defines “soldier” as follows:
‘[S]oldier means a person who served in the armed forces of the United States, or in any women’s organization, officially connected there*431with, during any war or armed conflict, in which the United States engaged, or who so served or hereafter serves in the armed forces of the United States, or in any womens organization officially connected therewith, since July 27, 1953, including service in Vietnam, and who has an honorable discharge from such service.
(Emphasis added.) Quite obviously, our initial inquiry must be to determine whether Petitioners fall within the above statutory definition.
In the construction and interpretation of a statute we must ascertain and effectuate the intention of the General Assembly and, if possible, give effect to all of the statutes provisions. Section 1921(a) of the Statutory Construction Act of 1972, 1 Pa. C. S. §1921(a).
Section 7102(a), 51 Pa. C. S. §7102(a), provides that the preference credits are to be awarded to a soldier “for the discipline and experience represented by his military training and for the loyalty and public spirit demonstrated by his service for the preservation of his country.” We believe that this is a clear statement of legislative intent. We also believe that one who serves in the Pennsylvania National Guard or in the U.S. Army Reserve receives the same discipline and experience of military training as those engaged in full-time active service and that the Guard or Reserve voluntary enlistments demonstrate the same public-spirited service for the preservation of our country as those who have volunteered or may have been drafted into full-time active service. It is true, of course, that the actual continuous time of service is different for those who are “regular army” and those who are in the Guard or the Reserve, but the same kinds of disruption in normal civilian life do occur, albeit on a lesser scale.
*432The Commission, relying upon an Attorney Generals Opinion3 and this Courts opinion in Greenwood v. Department of Military Affairs, 78 Pa. Commonwealth Ct. 480, 468 A.2d 866 (1983), rev'd, 510 Pa. 348, 508 A.2d 292 (1986), concluded that active duty for training was not the type of “service” contemplated by the Code.
The Attorney Generals Opinion4 relied upon Mitchell v. Cohen, 333 U.S. 411 (1948), which held, inter alia, that an “ex-serviceman” was someone who completely disassociated himself from his civilian status and employment during the period of his military service and thus experienced substantial long-term interference with his civilian life. The Codes definition of “soldier,” of course, contains no such limiting language; rather, the clear language of the statute is that a soldier includes any person who served or is serving in the armed forces of the United States. This Courts decision in Greenwood, which held that a Pennsylvania National Guardsman who was injured while-participating in annual training was entitled to compensation under the provisions of Section 844 of The Military Code of 1949,5 was reversed by our Supreme Court subsequent to the Commissions decision. See Department of Military Affairs v. Greenwood, 510 Pa. 348, 508 A.2d 292 (1986). Our Supreme Court recognized the state-federal dual character of the Pennsylvania National Guard and held that annual training which is federally funded is perva*433sively federal in character and not such state military duty as would qualify the Guardsman for benefits under the Code.
We note that each of the Petitioners has undergone training at federal installations, that both the Pennsylvania National Guard and U. S. Army Reserves are subject to call for duty and have been called for duty outside the boundaries of the United States, see 10 U.S.C. §§331—333, 672(a), 672(b), 673(a) and 673(b), and that both the state National Guard units and U.S. Reserves are an integral part of the United States Total Force Policy. We conclude that all Petitioners have been members of the armed forces of the United States within the meaning of Section 7101 of the Code.
It is true, as the Commission notes, that the terms “served” and “serves” are not defined in the Code. The Commission, as we have observed, was of the opinion that the service contemplated must be long term.
When this case was reargued, we directed counsel to address the implication, if any, of Section 103 of the Code, 51 Pa. C. S. §103, on the issue before us. That section provides:
It is the intent of this title that it shall be in conformity with all acts and regulations of the United States affecting the same subjects, and all provisions of this title shall be construed to effectuate this purpose.
The Commission now argues that that Section gives further weight to their decision because federal definitions clearly exclude Petitioners as qualifying for benefits. They indicate that 5 U.S.C. §2108(1)(B) defines a “veteran” eligible for federal veterans’ preference as one who has served on active duty, other than active duty for training, for a period of more than 180 consecutive days exclusive of service in the Army National Guard, Air National Guard or as a Reserve. “Active duty for *434training” includes full-time duty in the National Guard of any state, drills and field exercises for the National Guard and full-time duty performed by Reserves for training purposes. 38 U.S.C. §101(22)(A) and (C).
Petitioners, on the other hand, call our attention to Section 7109 of the Code, 51 Pa. C. S. §7109, which provides:
This chapter shall be construed as being the exclusive law applying to the Commonwealth, and its political subdivisions, in giving preference to soldiers in appointment or promotion to, or retention in, public position or on public works.
Petitioners also have traced the history of Chapter 71 of the Code. Whereas the Code is a substantial reenactment of The Military Code of 1949, formerly 51 P.S. §§1-101—1-1202, the preference provisions of Chapter 71 are derived from a separate and distinct statute enacted in 1945, Act of May 22, 1945, P.L. 837, formerly 51 P.S. §§492.1—492.8, repealed by Section 2 of the Act of August 1, 1975, P.L. 233.6 Section 103 of the Code is taken verbatim from Section 102 of the Military Code of 1949, formerly 51 P.S. §1-102; it was not a part of the Act of 1945 dealing with veterans’ preference. It was not until 1975 that the statutory provisions relating to veterans’ preference were incorporated as part of the present Military Code.
Furthermore, the purpose of Section 102 as it applied to other military matters, can be ascertained quite apart from veterans’ preference. Enlistment standards, uniforms, honorable discharge requirements are just a few of many areas where, for the sake of uniformity, state laws pertaining to the military must conform with federal standards.
*435The provisions of the United States Code previously cited are directed to veterans’ preference for federal employment. 5 U.S.C. §2108. Even the nomenclature is different: federal law refers to veterans who are “preference eligible” whereas Chapter 71 refers to “soldiers.”
For all of the above reasons, we conclude that Section 103 does not require that the provisions of the Code must conform with and be interpreted as a part of the federal legislation in the area of veterans’ preference. It follows that the active training which each of the Petitioners has undergone at federal facilities qualifies as service in the armed forces of the United States and that their service in the Pennsylvania National Guard and/or U.S. Reserves qualifies each of the Petitioners for the veterans’ preference provisions of Chapter 71 of the Code.
Order
The orders of the State Civil Service Commission in the above-captioned cases are reversed.
The cases were consolidated for reargument before a court en banc. We have been favored by a number of briefs from amici curiae.
The sole reason asserted by the Commission for disqualifying Strohecker was that he foiled to establish the requisite service in the armed forces of the United States.
Opinion of Attorney General T. McKeen Chidsey, No. 583, filed July 8, 1948.
An Attorney Generals Opinion while not binding upon a court is entitled to great weight. McDowell v. Good Chevrolet-Cadillac, Inc., 397 Pa. 237, 154 A.2d 497 (1959).
Act of May 27, 1949, P.L. 1903, as amended, formerly 51 P.S. §844, repealed by Section 2 ot the Act of August 1, 1975, P.L. 233.
In feet, it appears that Pennsylvania has had a Veterans’ Preference Act since 1887. See Preferential Treatment of War Veterans, 38 Pa. D. & C. 129 (1940).
