Modern (or modernized tanks) have reactive armor and other defensive equipment. In addition, modern tactics have tanks and infantry closely together so that tanks do not get served up as targets open to attack by guided missiles from opposing infantry. Disregarding that was how Russia’s tanks got chewed to bits in their attempt to take Kiev.

Close infantry will do no good. The Javelin has a 2500+ meter range and is a fire and forget weapon. Tanks are as obsolete as a battleships.
