Greece has modern tanks as well.
Leopard 2A6 HEL
1.7 billion Euros worth of brand new tanks in 2006-2009, and an additional 183 Leopard 2A4s and 150 Leopard 1A5 (for some sum I haven't checked)
National debt in Greece in 2006 was about 215 billion Euros - 103% of GDP. But Germany wanted to sell, and we won't hear any complaints from them about Greece's military spending.
