I like everything about this mod --very polished-- but can I suggest adding the carbine to Military 1 (red science) instead of Military 2 (green science)? The time it's most useful for me would be the first few fights to get rid of worms, before green science. I get grenades with Military 2.

Thanks for your kind words! 😊
New mod versions (2.0.1 for Factorio 2.0 and 2.1.0 for 2.1) has a startup setting to make it earlier technology – recipes get adjusted as well.

Sounds great. I will have to give it a look.
