My research, let me show you it

What I found out today is:

It's highly improbable that narching soldiers can collaps a bridge by creating a resonance wave.

So the soldiers that did collapse a bridge probably did it by being too heavy for the bridge.I tried to find out about archaic military discipline, but all I found out was that the goose step was invented to keep marchers at

I recall seeing film (it may have been Pathe News or similar newsreel footage) of the construction of the original Wembley Stadium. Once the stadium had been completed the engineers hired a large number of ex-WW1 soldiers to stamp up and down in unison to ensure the terraces were structurally sound.

And by the magic of the Internets and the all-knowing Google, here's a link to the footage, from 1923.

That's a very cool clip, thank you! Also demonstrating Mythbusters' conclusion -- that failure is a matter of structural soundness, not resonance!
