Not going to judge their outdated equipment. But they will fight. This a not Arabic troops from tribal societies who will run as soon as they are given the chance. In fact, North Korea CAN NOT lose this war. They have not lost the last one, they won't lose the next. North Korea is too important for both, China and Russia as a buffer country. Both countries have moved a lot of troops recently near North Korea. If there is a conflict we may seem a regime change (supported but Russia and China). What we are not gong to see is a US occupied united Korea.
One risk with Trumps pressure is they it works two ways. North Korea could reasonably assume that they will loose most equipment if the US attacks. So why not attack first? Use it or lose it. The safest place for a rocket or artillery shell is still in the air....
