What is tank defilade?

Tank defilade is a military tactic in which tanks or other armored vehicles take advantage of natural terrain features, such as hills or ridges, to conceal themselves from enemy fire and observation. This tactic is usually employed in defensive situations where tanks need to protect themselves from incoming fire while still maintaining a good position to engage the enemy. The position chosen for defilade should provide good visibility while offering cover and protection to the vehicle, such as a depression or hollow terrain feature. Defilade also allows tanks to use their armor protection to better resist enemy fire. Overall, tank defilade is an important strategy that allows armored vehicles to stay protected while still engaging in combat operations.
