This question already has an answer here:
War was banished from Earth, and instead operated by proxy on the Moon. Belligerent nations would each send robots (not necessarily androids) to the moon to compete for supremacy in the given conflict.
- The short story detailed a "world war" that was something like WW XVII or some other number well beyond II or III.
- The mechanisms by which they attacked each other were interesting; things like interfering with each others ability to isolate or dissipate waste heat while in vacuum.
I believe I originally read it in an Analog Magazine that would have originally been published in the 1970s or early 1980s.
