Simile
A simile is a comparison between two different things using like or as. In this the Air Force is being compared to eagles using the word like.
An understatement is a statement about the quality or condition of something that is actually less than it actually is. For example, "That car could use a day with the mechanic." In actuality, the car is so destroyed it probably needs to be considered a total loss and go to the junkyard. Rhetoric is persuasive speaking or writing. A hyperbole is an over exaggeration.
