Units with stupid weapon choices

[Wrana]

I meant needle ones - such as Russian Mosin-Nagant rifle had. I don't remember any "sword" bayonets except French ones - and these were used in trench warfare quite handily - without affixing them to rifles!
An offtopic question:
Agema, how well current M-16/M-4 plastic details withstand rough handling and/or using them in hand-to-hand? And another one - what are you supposed to do in case when dirt/dust gets into the barrel of any of these? (these appeared in recent off-line discussion with friends)
