That definitely isn't a complete list. It might be the most-recent package, but two items that I know that Germany has provided that aren't on there:
-
Leopard 2 tanks
Reading the page, it doesn't appear to qualify the list at all. Like, it doesn't say "for 2024" or anything like that.
The date is current, and the site claims to be a German government site (though I don't know the German DNS layout; the UK and the US and the EU have a specialized sub-domain for government sites and this doesn't appear to be under one, but I assume that this is indeed an official site).
