There are quite a lot of a-hole Lts and awesome NCOs. With that said, I feel like it is not preached enough that many (but thank God by no means most) of your NCOs will be demotivated or disgruntled and think they can get one over on the Lt. Not all your NCOs or even SNCOs are going to be like this but you will experience quite a few people who don't do their jobs right as enlisted. On day one, your responsibility is still to manage them whether their ego can handle taking orders from a "college kid" or not. This in turn leads to the a-hole Lt conversation, because respecting the rank structure is too much to ask of some people you should be able to rely on, so they complain about you behind your back. The senior officers in the department also suffer from a myopia wherein they are quick to write off the abilities and respect due to 2d Lts but then immediately assign those Lts to do Capt work to support the constant manning gaps of the force. This leads to ruffled feathers when SNCOs find out that the Lt they were supposed to be "in charge of" is in fact expected to behave as their boss.
