I guess the infantry was typically the “point of the spear”.

The armored divisions I think operated with infantry support. I suppose everyone had their job and they were all important but some were surely more dangerous than others.

Under Army doctrine, the primary mission of armor was to engage and destroy enemy armor, secondarily to facilitate the advance of the infantry by blowing defensive strong points. The mission of the infantry was to take and hold enemy territory.

In a combined arms team "support" is mutual.
