The Duty Faction does not allow entrance into their main base until after the Yantar X16 Lab Missions. However when you first arrive in Rostok you can immediately go to the Duty base entrance and go up the ladders to the roofs of nearby buildings and jump down to Colonel Petrenko and trade with him. Be wary of all other Dutyers inside their compound as they will turn hostile and try to kill you. The only way to escape is by squeezing between the debris between the two buildings west of him.Using this means you can acquire rare ammo and weapons from Colonel Petrenko that others don't have and the Inventory drastically improves upon the completion of a Duty Mission.
