Interesting. He spent the war serving in a variety of Commando units.
Weapons are tools. Each has advantages and disadvantages. At least a long bow is quiet and would be able to nullify a sentry at a short distance. Unlike the movies, where they turn down the sound, it is almost impossible to sneak up on a sentry and use a knife without them being alerted. I´ve even seen movies where the infiltrators are silently running over pebbles.
I served with a number of colleagues who were hell bent on being ´different.´
The sword isn´t such a disadvantage. He was relatively senior for the groups he worked in. In a previous life I was a section commander for a few years. I had 15 guys and 4 sub groups to control. I seldom got to fire my own weapon as I was too busy trying to focus theirs. I mainly carried tracer rounds. If I couldn´t accurately describe where I wanted a certain group to concentrate on then I could use tracer to guide them. Main problem with tracer was it could be traced back to me.
It was a last resort.
100 rounds of 303¨ would be in the vicinity of 3kg as that is he weight of a 100 round linked belt of 7.62 x 51 NATO (308). We had weapons that could spit out 200rpm for 2 minutes before the barrel had to be changed. Had 2 of those in the section so there is 12kg gone in 2 minutes from just one so 24kg total not to mention all the other guys pinging off too.
One of the reasons I´m a fan of 5.56 x 45. Weighs half as much so you can carry twice as many doses of discouragement.
A sword would also never misfire and its weight would be negligible in comparison. I imagine he´d be waving it around and yelling fire control orders. His weapons would be the men around him.
We had silenced sterlings instead of bows. Not bad when the suppressors were new but it didn´ take long for the noise to increase. Far from silent anyway as they are a blow back action but still only good for 50 metres or so due to the suppressor. Can´t really use suppressors on supersonic rounds. They still make a crack as they go by above the sound barrier.
Back to the eccentrics.
