What follows is an opinion from a United States Court of Appeals.
Intervenors who participated as parties at the courts of appeals should be counted as either appellants or respondents when it can be determined whose position they supported. For example, if there were two plaintiffs who lost in district court, appealed, and were joined by four intervenors who also asked the court of appeals to reverse the district court, the number of appellants should be coded as six.
When coding the detailed nature of participants, use your personal knowledge about the participants, if you are completely confident of the accuracy of your knowledge, even if the specific information is not in the opinion. For example, if "IBM" is listed as the appellant it could be classified as "clearly national or international in scope" even if the opinion did not indicate the scope of the business. 

Your task concerns the first listed appellant. The nature of this litigant falls into the category "federal government (including DC)". Your task is to determine which category of federal government agencies and activities best describes this litigant.

Before PHILLIPS, Chief Judge, and McCREE and KENT, Circuit Judges.
PER CURIAM.
This is an appeal from orders of the District Court granting and refusing to vacate or stay a preliminary injunction restraining the defendant-appellant from awarding a contract to the intervenor-defendant-appellant pursuant to an invitation for bids to furnish a quantity of 81MM shells for delivery to the United States Army in Vietnam.
We need not and do not reach the issue of whether the District Court had jurisdiction to issue the injunction pursuant to the provisions of the Administrative Procedure Act, 5 U.S.C. § 706, at the request of plaintiff-appellee gs a disappointed bidder. See Perkins v. Lukens Steel Co., 310 U.S. 113, 60 S.Ct. 869, 84 L.Ed. 1108 (1940); Scanwell Laboratories, Inc. v. Shaffer, 137 U.S.App.D.C. 371, 424 F.2d 859 (1970); M. Steinthal & Co. v. Seamans, 455 F.2d 1289 (D.C.Cir. 1971). Neither do we reach the issue as to whether the granting of the injunction was a proper exercise of the discretion of the trial court. We do not reach these issues because we conclude that the District Court abused its discretion in not vacating the injunction upon the representation by the Secretary of the Army that the National welfare will be materially affected by the injunction. On the basis of the affidavits on file we find the National interest to be of such overriding importance as to render the failure to vacate the injunction an abuse of discretion.
We have not been cited any authority in which any Court of the United States has enjoined the acquisition of munitions after a responsible officer has certified such munitions as necessary for support of troops engaged in military operations.
The cause is remanded to the District Court with instructions to vacate the injunction.
