Realistically, firing an automatic weapon into a sword fight probably isn't a good idea... and Darius hasn't exactly been focusing on training his men in melee combat.  They could try to wade in using the bayonets on their bolt guns... but waiting for a clear shot (while aiming) is probably smarter.<br/><br/>Thankfully, Baromir didn't need their help... (although I suppose having five guys with bolters ready to blow her away the moment he got loose from the assasin was a deciding factor in the fight ending right then... as she'd probably die if she didn't surrender at that point.)
