I've been quite impressed with spain for a while. I remember when that tank stuff started and pretty much every country then had excuses to send less than what they originally were thinking about - and spain announced they'll send less as the tanks are broken. It sounded like all the other excuses - but instead Spain steadily has been fixing and delivering way more tanks than they originally mentioned.
In relation to the tanks I think Spain said the quiet part out loud. European countries probably had a bunch of broken or missing military equipment that was never reported properly.
As an example, from Portugal, when the Tancos arms theft was discovered, the military prosecutors went to talk with "someone", and the thieves anonymously returned the stolen arms and some weapons that the army didn't even know were missing (shoddy bookkeeping on their day time job led to poor bookkeeping on their little hustle).
