Marines Seek Underwater Headsets

Headsets must work after spending two hours in 49 feet of seawater.

The Marine Corps needs some submersible radio headsets that can work after spending two hours in 49 feet of seawater.

I spent the better part of my youth as a Marine radio operator – including a lot of time hitting the beach from landing craft – and never needed an underwater headset.

Maybe someone from the Corps can enlighten me on this.
