What does "command presence" mean?

Dear all,

Could you help explain the expression found in an article about confined space rescue. Here is the sentence: "The attendant needs to be someone trained at the confined space technician level and have a good command presence and communications skills." Many thanks in advance!!

The attendant needs to look like s/he is in charge and knows what s/he's doing. S/he must have an aura of being in command. The attendant must look confident and competent in the event of an emergency.
