This is a review of the GI Joe Attack Cannon, FLAK. Unlike the other 1982 vehicleaccessories in two ways: FLAK is not a direct acronym and this is not a mobile accessory. Released in 1982 and re-released in 1983 and 1984 (in smaller standard boxes). In late 1984 to 1991, the FLAK was available for mail-order by Hasbro. The term FLAK comes from the famous German 88mm anti-aircraft cannon, although the GI Joe version does not resemble it.
