Ukraine

Belarus transferring equipment to their liege lord. There's been lots of questions about why Russia's vassal Belarus hasn't joined the war. Well - a good reason is that they have a tiny, ineffective army of less than 50,000 soldiers. For a very good reason - Belarus' army is designed to protect their muppet Lukashenko from domestic opposition, but remain small enough to not become independently powerful, or a threat to stand against Russia. While that makes perfect sense in keeping a weak vassal in power, it doesn't make for a good strategic depth option. If they're having to raid Belarus' tiny and even-more-outdated-than-theirs stocks, this is well and truly the bottom of the equipment barrel options for Herr Putin.
