It can consist of language or acts, however expressed. Disrespectful words refer to abusive epithets or any other denunciatory or contemptuous language.

Sentinels or lookouts perform a very important duty. The safety of the entire command rests on their shoulders and they are expected to remain vigilant and aware of their surroundings, at all time. If another service member comes around and speaks to him in a disrespectful language or behaves in a disrespectful manner, the sentinel or lookout can get distracted.
Consider that a service member is posted as a sentinel or a lookout. Another service member comes by and makes fun of the sentinel’s position and calls him names. The sentinel can get demoralized, which will reduce his ability to man the post. This cannot be allowed to happen.
On the other hand, if a sentinel or lookout loiters around, instead of standing at his post or sits down on the post, it is a sign that he is not taking his duty seriously. It may be a momentary lapse but it can jeopardize the life of other service members. This attitude is especially dangerous in war zones, where insurgents may be waiting lapses like this, to ambush US forces.
