I'm writing in the Stargate universe. Those of you that have seen SG1 and are familiar with the Goa'uld shock grenade and its use of light and sound as a debilitating effect - is that pretty much the same thing as a flash-bang grenade?
Are flash-bang's used in the US military? In what instances?
Is it correct what I've read in thrillers, to combat against the effects of a flash-bang, you try opening your mouth very wide, turning away or closing your eyes tightly and cover your ears? Does that actually work?
