I'd like to once again ask for missile series to be reintroduced.
It's one of the features I sorely miss from VB6 days. It made missile logistics so much easier, especially when new upgrades came in, or when shortages forced you to use older missiles. It enabled mixed missile loadouts, which is not really feasible with the current system.
Since ground equipment series is in the game currently, I hope that it's not too much of work to reintroduce missile series.
