"Robert traveled far into rural Vietnam to make a dental impression of Vietcong, who was spying for the United States. Barron would use the impression to create a disguise for the Vietcong, who needed to travel to sensitive areas, unrecognized, on information gathering missions for the American government."
I wonder if there's anyone who is generous enough to paraphrase this paragraph for me. According to my understanding, Robert made an impression of the Vietcong's teeth to help the Vietcong disguise himself for the missions. But I don't think it make any sense in logic. Thanks in advance.
