Charging - When an offensive player runs into a defender who has established position.
Consider what position the player plays. A defender should have good heading, shooting (clearance) and tackling ability. A midfielder needs to be a good all rounder. A winger should have good crossing, dribbling and speed. A striker needs to have good shooting (finishing), speed and dribbling .
In basketball, a defender is allowed to maintain their position under the basket, but they cannot use their body to push an offensive player backwards. If the defender uses their body to exert force and create space by pushing the offensive player several feet, it would likely be considered a foul for illegal physical contact. Proper defense involves establishing position without excessive physicality.
Anybody can be a good defender. Obviously, being short will hamper your effectiveness, as taller players can simply jump and shoot over you. However, there are many good defensive players that are undersized. You will generally play your position or smaller when guarding the other team, but you can easily become a great defensive player with hard work and practice.

If the attacking monster has lower ATK than the defence-position defender's DEF, then the defender is not destroyed at all. What will happen is the attacking player will take damage equal to the difference between the attacker's ATK and the defender's DEF, but neither monster will be destroyed.
