Such an infantryman would be quite vulnerable to a tank. Out sped (tanks can go > 80kph on terrain even fat-tired e-bikes would balk at), out gunned (excluding the cannon, there's also typically an anti-personnel mounted machine gun), out ranged (tanks can hit over 8k away), and without the anti-tank missiles, unable to damage a tank. It's why tanks came into being in the first place; they're quite capable against the average infantryman.
