BPOE members (4)
I believe the answer is:
elks
'bpoe members' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for elks that I've seen before include "Large deer of Northern Europe" , "Moose(s)" , "Moose" , "Large deer of Europe and N America" , "Large deer with flattened antlers" .)
