Yes, hit and run raids were part of both wars. However, guerrilla warfare is inherit to nearly all wars. Quantrill was a guerrilla leader against the North during the US Civil War; Francis Marion (the Swamp Fox) was a guerrilla against the Crown (Britain) during the American Revolutionary War. American Indians conducted guerrilla warfare against European expansion since the 1600s...and didn't end until 1890 (at Wounded Knee).
Constant alert for any hostile moves. If the Soviets entered the South China Sea, US forces were there to greet them. If the Soviets flew near Alaska, US aircraft shadowed them. If the Soviets had a fleet exercise near the US west coast, the US would be there watching (closely).

The Korean War proved to the both the Soviets and the Red Chinese, that a determined war to promote communism in Asia could be conducted. This theory saw fruit in the Vietnam War; with a communist victory.
Only when the Afghans began moving away from communism, and the Afghan government requested the Soviets to move in and help their government regain control; this was the Soviet Afghanistan war, which the Soviets (Russians) fought for close to 10 years and lost about 10,000 men fighting it. Today, those former Soviet veterans of that war consider themselves to be the Russian equivalent of American "Vietnam" veterans. Another words, the Soviets called Afghanistan their Vietnam. It's possibly a slightly comparable resemblance; but the Soviets (Russians) weren't fighting against the armed forces of Afghanistan, they didn't have to fight Afghan tanks, jets, and patrol boats nor a standing Afghanistan army. The US did in Vietnam; but other than that, both the USSR & US experience involved fighting many years in a small Asian country with thousands of fatalities.
