Ammo Can In Airplane Luggage? in Geocaching topics Posted January 2, 2006 According to this report you can buy a tank in Slovakia for US $2k, so surely empty ammo boxes are available! It says it costs the army $2000 to destroy a tank, not that you can buy a tank in Slovakia for $2000. Thats right. The Tank cost more or less about 1 million or more € But they have a lot of empty handgrenade- and minecanes because you can buy them for an buck or two. And this is not an joke!!!
