What does the “ORP” stand for in ambush terminology?

The term "ORP" in ambush terminology stands for "Observation Rally Point." This is a designated location used during operations where forces can regroup and establish observation points to monitor enemy movements prior to executing an ambush. The primary purpose of the ORP is to allow soldiers to get into a suitable position, assess their surrounding environment, identify targets, and prepare for their mission without being detected.

Having an ORP is essential because it provides a strategic advantage, enabling troops to observe enemy actions and maintain operational security. The ORP ensures that the first phase of an ambush is conducted with the highest degree of stealth and effectiveness, as soldiers can make informed decisions based on the information gathered from this vantage point.

Each of the other terms listed does not specifically refer to the method of positioning and observation critical for an ambush scenario, making "Observation Rally Point" the accurate definition in this context.
