FM/BG-502.V1.00 - How far to bound
The size of each bound should be based on the terrain, visibility, proximity of enemy threat, etc. For instance, bounds across relatively open terrain can be long - both in the interest of getting across as quickly as possible and because the range of the overwatch element is higher due to the open terrain. Urban bounds, on the other hand, are typically short due to the increased density of the area and the desire to maintain security and not overextend any one element.
