Task: Question Generation
Input (English): Passage: In 2014 Croatian arms exports reached 1.5 bn HRK (Croatian kuna) or €200 million or $257 million, the majority of exports being to NATO allies and Australia. In late 2014 the Croatian Defence Minister announced a major export deal to Iraq including the State of Kurdistan.  This agreement includes the sale of 20,000 VHS Rifles, 150,000 complete sets of uniforms, helmets and associated equipment valued at €100 million. Croatian arms exports are growing steadily at 10-15% yoy and were expected to reach 1.75 billion HRK in 2015 or around €230 million, although much of the equipment exported is non-lethal. Croatian firms are well positioned on some major arms tenders in the Middle East, supplying complex military hardware such as the Patria AMV incorporating a newly developed 30mm overhead weapon station (valued at €1.25 million each) and said vehicles valued at €1.75 million. Kuwait, the UAE, and Saudi Arabia have been mentioned as potential customers, although no concrete contracts have been signed so far. Croatian firms are participating in Kuwaiti and UAE tenders for next-generation APC programs, each valued at billions of euros.
