I think we will soon see mass use of mockups by the Russian army as well
Well, we know they've historically been great at producing military hardware that is, uh, missing some features. (Look up the Soviet "parade fighter," among other examples all' the way up to apparently sending "troops" to invade Ukraine with BB/pellet guns(!?))
On the other paw, kinda seems like they don't actually have anything that's at 100% to begin with so who's gonna know the difference.
