Arguable. Since the Strykers are now found in both Armor and Light Divisions (which remains to see how the neither fish nor fowl works there).
The Armored Corps down here seem view it as an Abram’s trainer. It has similar FCS and driver controls - so the ability to switch to a ‘real tank’ is much easier.
The previous version of the M-10 was a Tank Destroyer - so with some creativity this sort of is a modern continuation of that idea, with a gun in a sort of armored platform able to hit strong points and light vehicles while supporting Light and Medium Forces.
Now one of the biggest issues is this whole program flies in the face of US Army Light Force Doctrine - which says don’t do shit like that with light forces, and to use complex terrain and mobility to avoid the need for something like that, and that you have Medium (Stryker) and Heavy (Abram’s and Bradley) forces for those sort of fights.
