Yeah I missed the IFV part but yeah that is kind of what I would think. I just keep conceptualizing armored assaults as using tanks to punch through a line specifically so that APCs can get through and exploit the opening and quickly maneuver troops into position behind enemy lines.

I guess when you are talking about the most intense, heavily defended parts of an enemies defenses though I guess you aren’t banking on punching through just smashing the other side back. Doesn’t seem very effective though, tanks always outrun infantry.
