What was one advantage germany had during world war 1

They had a bigger army

Explanation:

One advantage Germany had during World War I was their ability to field to great effect their submarine fleet, which was able to suppress military and civilian supplies that were shipped to Great Britain, which greatly cut off the resources available to the island nation. Also, their ability to sink battleships, troop transports, cruisers, as well as the ability to damage coastal batteries, fortifications, and towns using the AA battery that was typically found on the deck of the submarines allowed for versatility of the submarines, and played a significant role in staving the onslaught of Allied resources poured into the west and Middle Eastern fronts.
