Just to expand on what cgilliam (hey friend!
) said, at my small boat station, we do have one ME. Even so, the MK's and especially BM3's here seem to do the lion's share of LE work. The ME does most of the LE and BTM-related training here, coordinating everyone's LE-related qualifications, training us on weapons, boarding protocol, and everything else. He also coordinates range dates and works with everyone on their marksmanship. I'd say he spends the vast majority of his time training others as opposed to actually getting underway for LE activities, although he does that occassionally too.
