This is entirely correct. A basic example is how the US doesn't prioritize SAM systems to the same degree as Russia. This doesn't mean the US isn't capable of producing similar or even superior systems at volume, it's just that it doesn't make sense given the overwhelming scale of the US Air Force. Likewise there's a similar relative de-emphasis on some forms of artillery.

Now after shaking off decades of counter insurgency warfare and pivoting to address a multipolar world instead it's not surprising they want to change up the mix. It doesn't mean there's some dire technology or capability gap fundamentally however.

Military stuff is entire operational systems vs other operational systems, yet nearly all these forum warrior conversations treat it as some sort of swipe left or swipe right pairwise comparison of two pieces of specific equipment.
