First World War combat degraded into an indecisive trench war stalemate
in no small part because communication difficulties made it difficult
to coordinate an attack. The war saw a great deal of innovation,
including communications innovations, and in part because of this,
successful attacks became possible. Signal Corps photos show some
of the technologies available during the war.
