It's not a nuclear hand grenade, but it's close.

For those of you who weren't familiar with this little Cold War artifact, here's the M29 Davy Crockett "atomic mortar" (actually a recoilless spigot gun). It used a teeny sub-kiloton nuclear warhead, which was the same one used in the Falcon air-to-air missile and the famous "backpack nuke" SADM man-portable nuclear demolition charges.

A battalion-level nuke gets funnier the more you think about it.

Can you imagine Corporal Snuffy standing by his launcher, waiting for weapons release to pass up to National Command Authority and back down to his crew while the T-55's of the Red horde poured through the Fulda Gap, bearing down on his battery's position? Yeah, me neither. If you had nukes within "I can hear loud noises" distance of the FEBA, they were gonna get used.
