This, my friends, is actually quite a genius idea. Him getting captured will probably avoid tantrums (especially with a new character to play in the meantime) but might learn him an important lesson. Particularly if an NPC mocks the ease with which he's captured, rushing into the guns of the enemy like that.

Have you tried explaining to him the difference between bolter shells and gum drops and why running headlong into one is far more lethal than the other

I think he knows that by now :/

Make sure he knows that not everyone will drop to the floor and cack their pants if you wave your rossette around as well

My players pulled that one on a den of slaught high muscle, didn't end well ^^

and yet, he continues to charge the machine guns as if they fired gum drops. Clearly, it must be explained to him. I recommend showing him footage of WWI as a visual aid.
