Nice euphemism. Not an invasion but a military operation.
I'm pretty sure when Wehrmacht entered Poland it was also a military operation, not an invasion to them. When the US went to Vietnam it was also a military operation. Does it change anything?
Civilians are being shot at, shelled, bombarded, their hoses bur, their children bleed. Stop spreading Putin's propaganda and accept the facts. They are using artillery and planes to bombard residential areas and lying to their own citizens saying that they're using precise strikes and targeting only military objects. Russia is one big joke starting from their lying politicians and ending with their junk equipment and lack of supply lines.

Yesterday some Russian soldiers run out of fuel and went to a police station to ask for some, where they were captured and disarmed. The stupidity of Russian army has no limit.
