Yes. Even things like the average speed of an advancing column of tanks, or the largest vehicle that can cross a particular bridge, are going to be fairly obvious to any army that has its own armoured vehicles.
Fun .gov overclassification anecdote: I worked for a startup that had a contract with .mil and, long story short, we needed a snippet of code that described soil slippage under load, as it remains the gold standard in the simulation of various things including armored vehicles.
IIRC, it had been originally written in the 1950s by the Army Corps of Engineers in FORTRAN (then C, then we used it with Modelica). It was — and is — still export-controlled. I had to get permission to send it to our UK (yes, UK) subsidiary for fear that said deeply dark secrets might reach the eyes of our enemies...
