A question for gun experts. (Page 3 of 20)

It's been written into AJB History, that the Rivalry between Higgins and ASP9MM is of legendary Proportions 

But your wife does remember him ! It's you she's trying to forget 

It's the trainers 

they aint trainers, they are glow in the dark boats 

I'm not a gun expert, but I think I can answer. Bayonets are there to make your rifle into a spear if you bullets run out or Your rifle jams. This was much more likely to happen in the past, but it still happens. This is from wikipedia:

In 1995, during the Siege of Sarajevo, French Marine infantrymen from the 3rd RIMA carried out a bayonet charge against the Serbian forces to regain the Vrbanja bridge.[38]

The British Army mounted bayonet charges during the Falklands War (see Battle of Mount Tumbledown), the Second Gulf War, and the war in Afghanistan.[39] In 2004 in Iraq at the Battle of Danny Boy, the Argyll and Sutherland Highlanders bayonet-charged mortar positions filled with over 100 Mahdi Army members. The ensuing hand-to-hand fighting resulted in an estimate of over 40 insurgents killed and 35 bodies collected (many floated down the river) and nine prisoners. Sergeant Brian Wood, of the Princess of Wales's Royal Regiment, was awarded the Military Cross for his part in the battle.[40]

British forces in Afghanistan have used bayonets many times. In 2009, Lieutenant James Adamson, aged 24, of the Royal Regiment of Scotland was awarded the Military Cross for a bayonet charge whilst on a tour of duty in Afghanistan: after shooting one Taliban fighter dead Adamson had run out of ammunition when another enemy appeared. He immediately charged the second Taliban fighter and bayoneted him.[41] In September 2012, Lance Corporal Sean Jones of The Princess of Wales's Regiment was awarded the Military Cross for his role in a bayonet charge which took place in October 2011

Obviously, the acts described above require BES (Balls of Enormous Size)
Personally I remember bayonet training in boot camp. We all found it very chilling and disturbing. 

I remember reading in a thriller borrowed from Barbel, that  sometimes
If you cut an enemies throat with, too sharp a knife, the two separate
Pieces of flesh may not separate and so fail at killing.
Don't know if that's a bit of writers imagination or in fact, er! A Fact.   
Also the groove in a knife is to prevent suction, leading to you not being
Able to pull it out to stab again. As Stag has said. 

I've heard that too, ASP9mm. But I do remember being tought to twist the rifle after bayoneting someone to ease the retraction of the bayonet blade. (Grisly, I know  )

Make sure to cross-check all these dodgy infos from him (Asp9mm) with google 

He's even dumb enough to lose his watch in a shower in the middle of nowhere and later buy a Bremont
