They just use more meat when adequate equipment lacks. See golfcarts, motorcycle attacks instead of using a bmp or some infantry fighting vehicle for example. No protection means higher losses. Also their tanks are older and older.

The sanctions help with making new hi-tech, and upgrading old stuff, what they do is just refurbishing old tanks and btrs (and building a handfull of each each month) but they’re scraping the bottom of the soviet stockpile as we’re speaking.

Maybe they will run out a month from now, we’ll see.
