Change flag by trigger

I have a mission where you must capture a town. For the first, I placed soviet flag and red marker. Then I made a trigger "OPFOR doesn't present" that changes marker color to green when all enemies are killed. Then I need soviet flag to change into Estonian (I have estonian flag with mod), is there's any way I can do this with my trigger?

This mission do that. but i don't know how to script.

I'm not really following, when the marker changes color just after it add the setflagtexture command https://community.bistudio.com/wiki/setFlagTexture

I know that I can use setflagtexture, thanks, but is there's any way I can place two objects (flags) in editor, make one "false", one "true" and then swap them by the trigger?
