Of course that was only for the country and it's inhabitants, Roland's Castle and the military were already in the early 25th century. He had removed the walls around every Town and City and built a "Great Wall" around his entire country. It was a very big project, 40m high, 25m wide, made of reinforced concrete with a 5cm wide plate of steel in the middle, but his Bots completed it in just a week. There was a tower every 150m along the wall, they were 55m high and were armed with 30 12.7mm machine guns, 6 20mm flak guns, 5 180mm artillery pieces, 2 12 barreled rocket launchers and a Small Stationary Railgun.
