First of all, he worked hard to prepare the KPA leading officers to get access to high-standard commanding abilities and latest military science and technologies.

He saw to it that all the leading officers had artillery commanding art in keeping with the demand of modern warfare and the Korean way of commanding artillery fire was introduced in rehearsals of all military units.

He also made big efforts to train each KPA soldier to be a stalwart combatant possessed of smart war tactics, good marksmanship and strong physical body.

Meanwhile, he gave priority to the nation's defence industry to arm the KPA with latest military hardware, raising the nation's military science and technologies to the world's level.

After all, the three services of the KPA have grown up to be armed forces fully prepared in striking ability, mobility and all other military technical aspects. The KPA naval and air forces are now ready to carry out any maritime operations and take supremacy in any kind of aerial warfare.

It is well known a fact that a KPA air force pilot drove the U.S. "RC-135" out of the DPRK's territorial air.
