Special military operation

"Special military operation" (also "special operation", and abbreviated as "SMO" or "SVO", or Russian: спецопера́ция, romanized: spetsoperatsiya, Ukrainian: спецопера́ція) is the official term used by the Russian government to describe the Russo-Ukrainian war. It is widely considered a euphemism intended to minimize the invasion and obfuscate the war's original objective of annexing all Russophone regions of Ukraine.
