This is an appeal from an order of Edwin P. Saunders, chairman of the State tax commission, granting taxation exemption on certain lands in the township of Grosse He, "Wayne county, Michigan.
The Michigan naval reserve airport is a unit of the United States naval reserve. The State of Michigan acquired a five-acre strip of land on the southern tip of Grosse He, on which it expended $100,000, and the Federal government expended $500,000 to establish and equip an airport, which, with land containing about 379 acres subsequently leased from the receiver of the Aircraft Corporation, a private organization, and the Curtis Wright Plying Service, Inc., is used by the Michigan naval force as a United States naval reserve aviation base.
With the exception of the five-acre parcel, these lands, buildings, and equipment were placed on the assessment roll for the year 1932 by the assessor of Grosse He township. Richard T. Brodhead, commanding officer of the Michigan naval force, protested the assessment before the township board of review, on the ground that the property was being used for military purposes and was not legally assessable under the laws of the State of Michigan; but the board held that it was not exempt, and refused to strike it from the assessment roll. On appeal to the Michigan State tax commission, an exemption was granted, and the plaintiffs appealed.
*453The question is whether the real and personal property in question occupied for military purposes as a United States naval reserve aviation base is exempt from taxation under the provisions of 1 Comp. Laws 1929, §§ 692, 3395.
Section 692 reads:
“Armories erected by counties, cities, private corporations, corporations composed of national guard companies or private individuals, and used by organizations of the permanent organized militia,' shall be exempt from all taxes ordinary or extraordinary, whether levied by the State or by counties or municipalities the same as other State property is exempt. ’ ’
Section 3395 reads:
“The following real property shall be exempt from taxation: * * * Tenth: All land dedicated to the public, and actually used as a park and any monument ground or any armory belonging to any military organization, and not used for gain or any other purposes.”
It is the contention of the defendants that, upon leasing the properties in question, they became a part of the “armory” operated as the Michigan naval reserve aviation base for military purposes.
The stipulated facts show that the Michigan naval force is a unit of the United States naval reserve organized under the national defense act of 1925 (34 USCA, § 751 et seq.); that from the aviation bases established in various cities there operate 22 naval reserve squadrons, 15 naval squadrons, and 7 marine squadrons; that the Michigan base is responsible for the training squadron, a fighting squadron, and a service squadron, which are important units in our national defense; and that the lands in question are adaptable to such use and are *454necessary to carry out the purposes for which the Michigan base was established.
There is no doubt that these lands are used for military purposes; but the plaintiffs claim that they are, not armories within the meaning of 1 Comp. Laws 1929, § 692, and are, therefore, not exempt from taxation.
To give the word “armories” the narrow meaning contended for by the plaintiffs would defeat the purpose of the statute, which, as indicated by its title, was “To increase the efficiency of the military establishment of the State of Michigan.” In its strict sense, an armory is a building where arms, ammunition, and instruments of war are stored, but in connection therewith it has been the custom to maintain grounds for drilling purposes and target practice. Such grounds are as much a part of the armory as the building itself. Together they constitute' a military establishment. New inventions and modern methods have increased the use to which armories are adapted. They have increased the instruments of war and the military needs in the use of armories. It was the purpose of the legislature to exempt from taxation all such military establishments. The lands in question are a part of a military establishment, and as such were intended by the legislature to be included in “armories” as used in the statute. They are, therefore, exempt from taxation ‘ ‘ the same as other State property is exempt. ’ ’
But it is contended by the plaintiff that the lands were not exempt when the supervisor of Grosse lie made the assessment and the board of review approved it. We think this contention is correct as to the Detroit Airport Corporation land. The lease of this land from the receiver was not approved by *455the United States district court for the eastern district of Michigan, southern division, until July 15, 1932. Negotiations for the lease were pending when the hoard of review held its final session on June 14, 1932, but it had not been obtained when the board had power to strike the property from the assessment roll. It was subject to taxation for the 1932 taxes at that time, and though it became exempt thereafter, there was no one clothed with authority to correct the assessment roll. See Iron Mountain Public Schools v. O’Connor, 143 Mich. 35.
As to the land leased from the Curtis Wright Flying Service, Inc., by the defendants, the lease was obtained on May 25,1932. The land was not subject to assessment at the time the board of review met, and should have been stricken from the roll.
The assessment against the Detroit Airport Corporation land for the 1932 taxes is approved. It should not have been stricken from the assessment roll. With this modification, the order of the State tax commission is affirmed. Other questions have been considered, but we do not deem it necessary to discuss them.
