I'm no expert on weaponry, but it appears that the military are/have been looking at Tungsten as a (possibly) safer alternative to lead/depleted Uranium. It MAY not be as safe as they thought. However I do note that DIME weapons are
SUPPOSED to reduce 'collateral damage'. (SMG beat me to it!)
Anyway, I've yet to see any definitive proof that DIME weapons are being used in the current campaign (not saying they aren't, but I'd like to see something other than an Iranian TV source).
