There is at least one U.S. military contractor whose main line of business is reballing RoHS-compliant SMT components with good ol'-fashioned leaded solder. Because the military depends on electronics that HAVE to work, for a long time, in hostile conditions, and could give two shits about the environment. The Army fires depleted uranium into the earth, you think they care about a bit of lead?

Actually oddly enough they're trying to not shoot as much lead into the Earth as they used to.

Assuming "green" ammo actually makes it into the field, we probably won't see it for a while.

Just putting the uranium back where it came from

To be fair, they're probably not aiming at the Earth.

Rule 4: Be sure of your target and what's behind it.

Aside from shipboard CIWS, it's pretty much always hitting the earth.

On the other hand, it's not that nasty.

You're aiming at whatever is in front of your barrel. Never point a firearm at anything you're not willing to destroy.

Besides, in this specific case, the whole point of DU is massive penetration, so of course it's going to eventually end up in the ground.

When you have a NASA failure lab implicating tin whiskers in the Toyota accelerator deaths we can call it more than 'annoying'.

source?

I'm aware of one major consumer electronics device which was redesigned at the last minute for RoHS solder, leading to very high failure rates.
