The A.C. trading caravan to Eastern Europe has returned with plenty of goods including old (was it BSSR?) weaponry such as the AK-47 and SKS rifles. The caravan even managed to buy an armored car. Preparation for another caravan to set off to Western Europe begins. Should anyone not want the caravan to pass through your lands, the caravan will just bring its business elsewhere, likely your neighbors or Eastern Europe.
Work begins on reverse engineering and manufacturing weapons that the caravan bought.
