However despite light tanks mostly being replaced by medium tanks, even in recon roles in the US army, light tank development separated and continues to this day due to ease of transportation and ease of use in amphibious and airborne missions, with recon taking the back seat until the 60's + 70's.

T-34/A32/A20 were replacements for the BT series, the M3 Lee was a replacement for Stuarts (well also technically UK cruisers) and the Panzer III + IV were replacements for the Panzer II. Britain by ww2 doesn't even use the heavy and medium definition, many cruisers and infantry tanks could fill both roles (more so the mid war infantry tanks). In both cases, outside of the British Vickers Medium tank, the vast majority of nations medium tanks were the direct evolution of what we'd now call light tanks, or what are light tanks in the HOI4 tech tree.
