What's in a name?
Avangard is the name of Russia's hypersonic missiles, which are thought to have been used against Ukraine during the ongoing illegal invasion. In June, Russian newswire TASS reported a second missile regiment armed with the weapons was to assume combat ready status.
Err.. I know it's not a reliable source, but-

The Avangard (Russian: Авангард; English: Vanguard; previously known as Objekt 4202, Yu-71 and Yu-74) is a Russian hypersonic glide vehicle (HGV) that can be carried as a MIRV payload by the UR-100UTTKh,[7][8] R-36M2 and RS-28 Sarmat heavy ICBMs. It can deliver both nuclear and conventional payloads.
I don't think things have gotten so bad that Russia's launching ICBMs. Yet. I also rather hope they're not likely to, especially as the EU's busily shipping ABM defence systems to Ukraine. While at the same time hyping up the threat of Russian nuclear strikes. The logic escapes me, but then I'm an engineer, not a politician.
But Vanguard is a common word, used in many places. Like our current class of SSBNs. Or in an Extreme sense, some neat little routers-

Which were previously Motorola, then Vanguard, now Raymar. Also were rather good from a price/performance/features PoV. First encountered when I well-known high street retailer asked if we supported them. Errmm.. But client was using a nifty lil router that had built-in wireless and 3G for around 1/3rd of a Cisco's deck of cards. And a far simpler (and cheaper) support model. But I digress. If Extreme sold tin to a company on an export control list, that's an oopsie. But that's also sales. The price of eternal freedom is eternal vigilance, especially for anyone who's worked in sales and knows they should be watched closely to prevent situations like this. Especially in 'sales driven' companies who care more about commissions than seeing their execs end up in jail. Especially if they're American execs.
