- Name
ChokePoint- Kind
- FeatureType
- Definition
- A length or single point along a route that due to its width, surface quality, alignment, fixed human activity or fixed human feature is likely to impede movement at a constant speed resulting in slowing, and either by vehicular bunching or by type may cause temporary halts.
- Description
- In military strategy, a choke point (or chokepoint) is a geographical feature on land such as a valley, defile or a bridge, or at sea such as a strait which an armed force is forced to pass, sometimes on a substantially narrower front, and therefore greatly decreasing its combat power, in order to reach its objective. A choke point can allow a numerically inferior defending force to successfully thwart a larger opponent if the attacker cannot bring superior numbers to bear.
