I fail to understand, then, why these rebels did not use them against the FSU. It would have been easy.
Also, what is the shelf-life of low-shielded compact devices?
Thermal degradation of the implosion charge (These things are *warm* to handle), as well as y and N degradation imposes a "Best if used before...." date on them.
Reliability isn't a big concern with these guys. Just HAVING the weapon is a big enough factor.
Then again ... I think, if anybody actually HAD such a weapon, they'd boast about ... or would have used it already.
A nuke is ONLY effective (unless exploded) when your opponent knows you have it. Here, a hidden threat is no threat at all.
