The US soldiers observed demonstrations and took part in rice growing, rice harvesting, buffalo raising, organic fertiliser making, clay house making and they also had some fun with Thai traditional games, said Thai unit head Lieutenant Colonel Somsak Theskham.
The group's visit was joined by students from nearby Ban Nong Wa Sathit School.
The cultural and leadership promotion programme was provided in Sa Kaew, Nakhon Nayok and Chacherngsao provinces and involved 33 US soldiers.
The Sa Kaew activity was held on Wednesday and Thursday, while another two groups had visited Sa Kaew on May 23-26 and May 30-June 2. They will return to Nakhon Nayok later today before heading to Bangkok and then back to the US, he added.
