Hungary and Czechoslovakia
The USSR invaded Hungary in 1956, Czechoslovakia in 1968, and Afghanistan in 1980.
When faced with opposition the USSR would always send in the tanks.
After WWII, Poland, Hungary, Czechoslovakia, Bulgaria, and Romania became the USSR's satellite states.
The USSR took over Czechoslovakia on August 20, 1968.
The USSR dealt with challenges to its control in Hungary and Czechoslovakia through military intervention. In Hungary, the 1956 revolution was suppressed by a Soviet invasion, restoring a pro-Soviet regime. Similarly, in Czechoslovakia, the Prague Spring of 1968, which sought to implement reforms and greater freedoms, was crushed by the Warsaw Pact invasion, reaffirming Soviet dominance in Eastern Europe. These actions demonstrated the USSR's willingness to use force to maintain its influence and prevent any deviation from its control in the region.

In both instances, citizens sought to challenge Soviet dominance and implement liberal reforms. The USSR reacted decisively by deploying military force; in Hungary, Soviet troops crushed the uprising within weeks, while in Czechoslovakia, the Warsaw Pact invaded to suppress the Prague Spring, restoring a hardline communist government.
