In 1997, Hungary spent about 123 billion HUF (560 million USD) on defence. Hungary became a member of NATO on 12 March 1999. Hungary provided airbases and support for NATO's air campaign against Serbia and has provided military units to serve in Kosovo as part of the NATO-led KFOR operation. Hungary has sent a 300 strong logistics unit to Iraq in order to help the US occupation with armed transport convoys, though public opinion opposed the country's participation in the war. One soldier was killed in action due to a roadside bomb in Iraq. The parliament refused to extend the one year mandate of the logistics unit and all troops have returned from Iraq as of mid-January 2005. Hungarian troops were still in Afghanistan as of early 2005 as part of the International Security Assistance Force. There were reports that Hungary would most probably replace its old UAZ 4x4 vehicles with the modern Iveco LMV types. Hungarian forces deploy the Gepárd anti-materiel rifle, which is a heavy 12.7 mm portable gun. This equipment is also in use by the Turkish and Croatian armed forces, among other armies.
