I counted around 30 Abrams. I don't necessarily think the number is "excessive", but the basis of comparison is Russia, China, and North Korea. For those, "excessive" is kind of the point of these things.
There was one time where the Soviet Union recycled one flight of bomber planes over the parade grounds multiple times, to make it look like they had more bombers than they really did. This resulted in the "bomber gap", causing the US to massively increase its spending on strategic bombers.
