personal battle

[unpakwon]

What kind of battle is "a personal battle" in the following?

One should never forget that the Korean War was primarily a very bloody, up-close, and personal battle between Chinese and American troops.

Does this mean "a hand-to-hand fight, or close(tight) battle"?

Thank you.

The phrase is "up close and personal" I have never seen this with a comma after "up close". I would take it to mean that the Korean war was actually largely fought between American and Chinese troops rather than Korean troops.

And also that the fighting was vicious and passionate.
