Carry weapons with sleeves rolled up, reportedly (4,4)
I believe the answer is:
bear arms
'carry weapons' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for bear arms that I've seen before include "Serve in the forces" , "Serve as a soldier" , "Carry weapons" , "they may be used in a tight squeeze!" , "right for American?" .)
