If a SFT is marked with the same number earlier than the one you are looking at, then it will show up as the first one marked with the number. (Or is that too technical?)
For instance if rifle I was marked first in the editor as that reinforcement type, then in the TO&E it would show as that, even if rifle II was researched. However if Rifle II was first in the list of SFTs, then it would show Rifle II first.
Perhaps the Halftrack in question is marked as an earlier mark as well.

I have not seen anyone mention it but I am getting winter weather in the middle of year (July/Aug in addition to normal time) when I do a random game using Temperate climate (may have used other climates in past with same result). Weather generation does not seem to understand that game has 2 week turns instead of monthly. Have you guys been using "no" weather or is it just me.
