newb to squaddie promotion

[hellblade]

This is really minor, but could squaddie promotion be shown as well?
Promotion always bring joy to players, even if it's lowly squaddie promotion.

Plus it's also easy to implement.  I wonder why it was never shown before.

Sure, no problem.

I imagine the reason it wasn't shown before was because it's not part of the typical promotion process, just a "kills > 0" check.
