Well, the Ethics thing and the badger are about making people vote for the ethics thing, because I doubt that I will get the votes for an international arms moratorium without taking it onto something good, like the badgers. So that has nothing to do with multiple proposals and everything to do with vote manipulation.
The modified badger proposal is for the modified badger proposal. I liked the idea of external machine guns positions, but Felt that it was a bit much for a light tank, so I mad the modified proposal, which is still valid under voting rules and lets folk choose which tank they want. And as awesome as the K-1 might be, and upgraded badger is really more practical for the current battlefield.
The anti-glare sights and the balloon really are just components on the destroyer. But I started with the idea for the sights so I made that the focus. As for the destroyer, well, we need something to help out our merchant fleet and I think that the worker's destroyer is the right ship for the current job. I would rather give it a 320mm gun to out0range everything, but that just isn't going to happen. I would like to give it the armour to take a few torpedoes, but you really have to pick either speed or armour, and speed seems preferable. Moree guns would be fun, but its deck is already going to be crowded. A twin turret would be nice, but it really isn't there to out-gun anything, and the one 169mm should be plenty for sinking subs at range and sinking merchant ships that refuse to surrender. Do long story short, Proposal 5 is just one design with a few different innovations, and proposal 4 is a design proposal and an ethical proposal, which really isn't as much as a design proposal, and the reasons for combining them have nothing to do with bypassing the proposal limit. And 4.1 Really is a legitimate modification of 4.
