This is a quick and simple mod which tries to address the issue of late game battles falling into tedium due to massive defense and inability to do real damage. Essentially, I've given the machine gun tech a +10 to attack in addition to the +5 to defense, and also double the attack bonus of every level of artillery increase. This should drastically increase attack values across the board, and make late game combat extremely deadly.
I have not had the time to extensively test this, as it is just myself, so if you download it, and have any comments on whether it's too much, or not enough, please feel free to post here and let me know. I'd love to know before and after values of attacks if you happen to load my mod in the middle of a save game with a battle going, as it will provide me with a lot of feedback.
I've attached the rar file to this post, feel free to visit my webpage for the mod as well, which also contains a general bugfix mod. You can extract the rar directly to your main directory, I've included backups of the files changed, so there will be no issue with overwriting files, and you don't have to backup the files yourself.
Edit: Did some more testing, found out that it didn't make a big difference, so I also drastically lowered military tactics gained per level, and that seems to have done the trick, combat is a lot more decisive now.
