During World War I the Germans used many different types of naval weapons including a large fleet of battleships. The most effective naval weapon that the German army had was the merchant u-ship submarines.
The most fundamental change that the aircraft carrier introduced to warfare was extending the range of naval fleet's effective firepower. This was made possible by the airplane. Prior to the inclusion of aircraft in the naval equation, the farthest offensive range was based on the fleet's biggest guns (on the battleships). With aircraft carriers, the range was extended by a factor of more than 10.

Effective? The North Vietnamese were the most determined. Effective? The United States had the most firepower.
"Guerrilla Warfare" was the most common type of fighting used by the North Vietnamese during the Vietnam Conflict. This kind of irregular warfare is characterized by small groups of mobile combatants who ambush, raid and harass their enemies. The purpose of Guerrilla Warfare is to weaken the resolve and resources of the enemy and force them to withdraw. These small groups of fighters generally avoided large battles and chose their targets carefully to minimize losses. This is one of the most effective tactics used when fighting an enemy with overwhelming numbers and resources.
Trench
Of course (while not entirely new) the proliferation of the machine gun forced the type of warfare that ensued.
Trench Warfare. AKA: Slaughter (men getting in the way of machines)
Gas warfare would have been the warfare conducted by using poisonous gas to clear out trenches during WW1, but even during WW1 when gas was the most common, it still wasn't used excessively as it was viewed as an evil way to fight.
Britain was most powerful due to its naval superiority and industrial advances.
It changed naval warfare for ever. As soon as the British heard about the battle they immediately set to work to armour their navy.
