Defenders may retreat after 1 round of combat

[iratoric]

I'm proposing we add an option where defenders can choose to retreat after 1 round of combat, like subs in the classic edition, but this would be able to be utilized properly by land units without all the undesired side effects of making it a sub. Not only would this add more strategic options, it would also be a lot more realistic. Could be a game property.

Worked on this on a fork and made a pull request here: https://github.com/triplea-game/triplea/pull/14649
It seems like it's failing a test with a few of the old save games though, can anyone help?

Example of what I am seeing when I run on my machine:

Hi ira

What triplea engine version are you using ?

[iratoric]

NVM I got it working. The pull request now passes all tests! Now I can only wait and hope that it gets picked up. @beelee The version of TripleA is whatever the very latest unreleased version is from Github.

@iratoric Did you implement defender retreat as a game property?

[iratoric]

@RogerCooper Right now it is on my branch as "Defenders Can Retreat Battle Round" as an int property where you can select what round defenders can retreat (-1 is the default and means they can't, 0 means before combat, 1 means after 1 round of combat, etc.) There's been a discussion on GitHub but I should probably make another topic for discussing it here, the questions now are mostly how it should be implemented

@iratoric That sounds like a useful addition to the TripleA engine.

@RogerCooper Thanks, I just made a post to poll people's opinions on how it should work in Development, be sure to give any opinions there
