If this in StarCraft I? In StarCraft II even a burrowed zergling can prevent the landing of a Command Center. (That makes no sense from a realistic point of view.)

In principle, you could do this with any unit, but it was mostly useful for siege tanks, since those were the only Terran ground unit which really benefited from sitting in place.
Killing the tank was the "creative" solution, instead of a "brute force" solution to change the game dynamics to prevent the tank from sieging up under the building in the first place.
In SC2 the tanks will be forced to move out from under the building when it lands, but SC2 also has a much improved unit movement system over SC1 that allows this to be done more easily.
Search on YT for the tank glitch.
