An ambush is defined as an attack from what type of position?

An ambush is defined as an attack from a concealed position. The essence of an ambush lies in its element of surprise, which is achieved when an attacker uses the environment to hide their presence and intention until the moment of the attack. This concealment allows forces to remain undetected, catching the enemy off guard and minimizing their ability to react effectively. The success of an ambush relies heavily on the attackers being hidden from view until they choose to engage, making a concealed position critical to the ambush tactic.

In a broader context, while open positions might offer visibility and freedom of movement, they lack the advantages of stealth and surprise necessary for a successful ambush. Flanking positions do can surprise an enemy, but they do not inherently provide the same level of concealment. Fixed positions may offer a strong defense but do not contribute to the surprise element that defines an ambush. Thus, the characteristic of being concealed is paramount in the practice of ambushing and is why this response is the most accurate definition.
