I've been rewatching the series The Pacific and something occurred to me. Pop culture and several books that I have read give the perception that most Marines who fought in WW2 carried a Ka-Bar (Mark 2 Fighting Utility Knife). The problem is that most of the Infantry would have had bayonets which goes against the perceived common use of the Mk2. Some weapons couldn't mount a bayonet but this would have been the exception, not the rule. Out of 13 Marines in a rifle squad only three of them carried automatic rifles, everyone else should have had a bayonet. My theory is that many of the authors who wrote about their experiences weren't in rifle squads (survivor bias?). So perhaps the books we read about the pacific theater in WW2 overemphasize how common Mk2s were? Maybe some marketing help from the KA-BAR company is at play as well? Does anyone have any evidence about this one way or the other? As a side note, I wonder if Army personnel in the pacific theater had any affinity for the M3 fighting knife.
