The Channel Tunnel is a conspicuous dependency in plans to reinforce Poland or the Baltic region. An attacker would not need to destroy it permanently; a mission kill lasting several days could delay a brigade long enough for opposing forces to consolidate. Rail tracks, power, trains, and loading arrangements create several ways to interrupt the route even when the tunnel structure survives. This vulnerability strengthens the case for amphibious vehicles and sea lift that provide an alternate path rather than merely a slower version of the same plan.

The Channel Tunnel as a modern deployment bottleneck
Moving a British strike brigade by rail creates a predictable point where a short disruption can buy an opponent valuable time.
