I'd dare say a large issue for European militaries has been the procurement process. At the moment there's a minor scandal brewing in the Danish military, over the purchase of a number of howitzers from Israeli company Elbit. First, it appears that the decision to buy them were a quid-pro-quo deal, where Elbit would drop a lawsuit against Denmark, in exchange for Denmark buying their howitzers. And second, said howitzers are apparenly using GPS systems that are vulnerable to jamming, meaning they'll have to be rebuilt or replaced.
