Anyone who thinks the Russians are being sloppy are believing propaganda. The Russians are acting methodically. They have 60,000 Ukrainian troops in "cauldron" in Eastern Ukraine. They are encircled. There are four such "cauldrons" that have formed. Cities are encircled.
The only reason the Russians are showing restraint is because they are trying to force a negotiated settlement.
Methodical piss poor execution of military tactics.
Restraint? They are leveling population centers, targeting civilians purposefully.
