after tedious reconnaissance and the occasional dogfight between opposing soviet aircraft, Japanese forces have pinpointed what they could find of artillery guns, two battalions that had been hiding in the Manchurian mines have came out of hiding and are now advancing towards know locations of guns (I've told Jairo in advance I was hiding them), once the guns have been reached the soldiers are instructed to de-crew the guns and demolish them to their best ability - after that is achieved / not achieved they are to leave marksmen near the sites to pick off soldiers that come back. another handful is tasked to go search for munitions depots or camps of the soviets and apply demolition charges to the cause.
the rest of the force is to take type 97 automatic cannons and flank the Russian advance on the Korean line.
Japanese soldiers, after a large friendly bombardment on the advancing soviets attempt to push back the soviet aggressors with a large push from the defensive line.
given soviets forces are close enough, the Japanese navy bombards the coast.
