Select the word or phrase that is redundant and can be removed without changing the meaning of the text. Combat canines in the U.S. military played an essential and important role in finding improvised explosive devices, or IEDs, during the war in Afghanistan. Submit

The word "essential" is redundant because the term "important" already conveys a significant meaning. Therefore, the phrase would still retain its meaning without it: "Combat canines in the U.S. military played an important role in finding improvised explosive devices, or IEDs, during the war in Afghanistan." For a bit of historical context: Military dogs have served alongside soldiers for centuries, dating back to ancient civilizations like the Greeks and Romans, and have been used for various roles including sentry duty and attack. Their prominence surged during World War I and II, with many breeds specifically trained to assist troops on the battlefield, paving the way for their crucial involvement in modern conflicts like those in Afghanistan. And let's not forget the paws-itively amazing bond that forms between these dogs and their handlers! Proper training and communication can lead to a highly efficient working partnership, but a common mistake is underestimating the emotional needs of these canines. Ensuring they receive ample socialization and exercise can prevent behavioral issues and enhance their performance in their vital roles.
