What type of individual movement is preferred when cover and concealment are available, requiring speed?

The preferred type of individual movement when cover and concealment are available and speed is necessary is the high crawl. This method allows an individual to maintain a low profile, minimizing exposure to enemy observation and fire while also enabling more rapid movement than other methods like the low crawl or rush.

The high crawl involves moving on the hands and knees, which provides a balance of speed and tactical advantage. When cover and concealment are accessible, using the high crawl permits personnel to advance quickly while still remaining relatively hidden. This technique is especially useful in situations where terrain provides adequate protection and an urgent need to maneuver exists, making it ideal for advancing toward an objective or repositioning during a conflict.

Other movement types, such as the low crawl, sacrifice speed for a lower profile, and the rush is typically used when quick movement is required, but it compromises concealment and increases the risk of being spotted. The combat roll is more suited for evading enemy fire than for sustained movement, further emphasizing the high crawl's superiority in scenarios where both concealment and speed are critical.
