One thing I will say is that this would be a much better improvement if:
- It came out as a global upgrade for like 200mp - 30 fuel at T3.
- It did not affect the cons weapon slot
There is another way though. If you're hell bent on penals always being the mainline and cons having a utility role, then why not make the ptrs package from tank hunter available without a commander? Conscripts having a pure utility/AT role would synergize much better with the way the faction currently works.
If it didn't took weapon slot, it would make PPSH and PTRS(AT nade assault) cons insane.
Again, if it proves to be insufficient, just slap between 5 and 15% accuracy on the upgrade and call it a day.
Additional man do help a bit, especially since that one extra model is pretty much always sniped on approach, leaving "vanila" 6 man con to actually engage.
Make sure the upgrade doesn't hog extra pop and if needed give slight bonus accuracy and it'll be exactly what cons need.
