American Battle Tactics
Americans did not have a good starting fight at their beginning of the Korean War. They fought desperately at the beginning and delayed operations but it was hard to hold back North Korea's advancing forces. By July North Korea had pushed U.N. forces to the southeast corner of the peninsula.
Warfare
Americans based how they fought on specialized attack such as night attacks and they also used lots of guerrilla warfare which is like hit and run where you would pop out from behind a tree, shoot at someone, and then dodge behind another tree. Lots of the war was also very basic such as how forces fell back and moved forward a lot and it wasn't just all over the place.
