-UI: Chaebol Enterprise- +4 gold, +3 production.
UU: Hyangto Yebigun- Replaces great war infantry. Cheaper and weaker than Great war infantry. Can be upgraded from workers.
UU: Ulsan class- Replaces destroyer. slightly cheaper, gets 15% combat strength bonus when attacking land units.
and some UBs...
UB: Cheongwadae- Replaces palace. has 2 merchant slots.
UB: POSCO Steel mill- Replaces factory. doesn`t need coals.

This mark is for Saemaul undong, and since the Saemaul undong is one of Park`s greatest work, I think that would be nice, too.
