What major innovation in tactics did the UDTs contribute to amphibious warfare?

The UDTs (Underwater Demolition Teams) innovated amphibious warfare by utilizing small, agile boats for reconnaissance and demolition missions. This approach allowed for precision scouting of enemy coastline defenses before larger forces landed, greatly enhancing operational success. These teams expertly navigated shallow waters and performed demolition work to clear obstacles such as minefields and beach fortifications, which directly facilitated the larger amphibious assaults.

The use of small boats provided increased mobility and flexibility, allowing for stealthy operations and quick extraction if necessary. This tactic contrasted sharply with reliance on larger, slower vessels, and it marked a significant evolution in how naval forces engaged enemy positions during amphibious operations. The strategies developed by the UDTs laid the groundwork for future special operations tactics and demonstrated the importance of specialized teams in modern warfare.
