every year. The Croatian Army is being reorganized to fit in the NATO doctrine of a small, highly capable force with an emphasis on mobility and versatility. Major combatant commands of the Croatian Army are one armored and one mechanized brigade, each brigade having a specific role and different responsibilities. In 2012, one motorized infantry company is to be detached and put under the command of the EU Battle Group led by Germany. Croatia continues to deploy 350 personnel in support of NATO International Security Assistance Force in Afghanistan. Croatia achieved NATO membership in April 2009. The defence reforms that Croatia initiated in 2000 have a long-term goal of replacing and modernizing the armed forces to meet the challenges of NATO membership. The plan calls for the modernization of the Army and the introduction of training and doctrine in line with Western (NATO) standards. Replacing ex-Yugoslav/Soviet hardware is also one of the main priorities. There are various ongoing initiatives, such as the upgrade of the tank fleet, introduction of new Armored Personnel Carriers and NATO standard assault rifles, etc. Procurement of new, NATO-compatible equipment takes a significant part of the defense budget. Until less than a decade ago, Croatia had operated just under 280 main battle tanks, but this number decreased significantly due to the withdrawal of roughly 200 obsolete T-55 tanks in 2006. Most of these units have been scrapped, but a limited number have been stored as operational reserve in case of need. The mainstay now are the M-84A4 Sniper main battle tanks which are currently undergoing overhauls. However, modernization of the tank fleet to the M-84D standard is also envisaged. In July 2007 Patria AMV won the contract to supply the next generation of APCs to the Croatian Army. Only 84 vehicles were ordered at first with an additional 42 purchased in an extended contract signed in December 2008. Croatia now operates 126 units with the first six vehicles manufactured in Finland and delivered by late 2008. All remaining vehicles have been locally produced by 2014. Out of a total of 126 units, 112 are armed with 12,7 Protector (RWS) remote controlled stations. In early 2007, Croatia bought 10 Iveco LMV light armoured vehicles at a cost of 330,000 Euros per unit. According to official documents, 94 of these vehicles were needed by 2017. However, Croatia now relies on over 200 US-donated HMMWV and MRAP type vehicles.
