Air National Guardsmen from Massachusetts and California are deploying with F-15C and other equipment to Iceland and the Netherlands in order to counter Russia according to an April 2, 2016 press release from the 104th Fighter Wing of the Massachusetts Air National Guard.
The Guardsmen “will support the NATO Air Surveillance mission in Iceland as part of a Theater Security Package in support of NATO alliance commitments" according to the press release. Guardsmen also will be positioned at Leeuwarden Air Base in the Netherlands as well as with “other European NATO and partner nations.”
And while the press release says that, “Units will conduct training alongside our NATO allies and partners to strengthen interoperability and to demonstrate U.S. commitment to a Europe that is whole, free, at peace, secure, and prosperous and to further Russian aggression [sic],” the U.S. federalizing and deploying the Guardsmen is meant to counter further Russian aggression.
The following B-roll video, also released by the Massachusetts Air National Guard, shows some of the Guardsmen F-15C aircraft taking off. The last 4 seconds of the video (starting around 1:28) also shows Col. James Keefe, commander of the 104th FW, talking about how the federal government is using the National Guard to fulfill strategic missions and needs.
