I'm at a loss as to WHY this would be offensive? Iraqis have kitchens, don't they? Can you explain this?
Also, why aren't US forces just issued one knife, a bayonet?
From what I understand most bayonets have lousy steel, and aren't sharpened. Wouldn't a single real knife with a bayonet fitting make more sense, in terms of cost, weight, and practicality?
Cost. A properly heat treated blade of good steel will be far more expensive to make than a bayonet.
The PC mindset is that knives are offensive in nature and appearance to most. It falls into the 'hearts and minds' stuff the military does. It's also scaling of threat. The look of 100 Marines fully tooled up, swathed in belts of ammo and 1 in 4 packing a MMG is far more intimidating than the same men with soft covers on, M4's and only maybe 1 MMG per 8. It's all part of a strategy, it's up to you if you think the strategy right or wrong.
In my own experience I had a couple of knives, KaBar and F/S Commando Dagger, visible on my webbing in Iraq and Afghan. Both times we were 'war' fighting and I was not told even once about putting them away. In fact due to the aggressive nature of my appearance I was used multiple times to escort officers and aid in questioning of locals.
The broader scale of the article worries me more. Binning 5 mile speed marches and bayonet drills to me is lunacy. The drills practice aggression and are physically exhausting, the 5 mile runs are good for conditioning not just fitness but joint strength and stamina. British troops are patrolling far longer distances than 5 miles so this short sprint, zig zag stuff is only really good for MOUT/OBUA. My fear is the revamp of training sees soldiers trained for very specific scenarios or theaters and this can lead to casualties if the enemy changes his tactics or locations to fight in. To use a knife comparison a soldier should be like a KaBar, not a scalpel not an axe. Somewhere in between that can do most jobs well while failing at none. SF or specialist units do the other stuff.
In the UK I know for a fact that there is a dedicated program running to prevent the loss of traditional training in a 'green' role. The focus on Afghan and Iraq can blinker training establishments, but having learned from previous wars it's a lot easier to lose skills and knowledge than it is to relearn them.
As regards the types of combat being taught to our military today, I don't really won't to go into it apart from to say MMA has a lot to answer for as regards what people think will work on a battlefield in full kit.
