Why the military combatants and the Boy Scouts campers needs superglue?

Superglue, though medically not advised can perfectly bond your skin. 

Remember that little accident when your child suddenly squeezed a punctured superglue barrel in his hand?
You can learn from that superglue characteristic to your advantage.

If you incised your skin and you have troubles clipping the lipped flesh wound back together,the superglue can be your first aid rescue, until a proper medical assistance is available.

Superglue sticks even on wet surfaces.
In wounds, you just have to be careful not to put its gel into the open flesh .

So that's why combatans and campers must carry a superglue everytime, in case of accidents, to prevent profuse bleeding.

Of course it is not a proper medical procedure but at least you can ease the open wound a bit until a doctor arrives or until you get the patient
to the hospital.
