Sgt. Watson was seen somewhat during the starting hour of the film. He can be seen vaguely walking with the team when they first arrive in Da Nang. He really didn't come to the forefront until they were several days settled into Camp A 107, when Capt. MacDaniel ordered him to arrange sleeping quarters for the arriving Seabees. He was also seen playing a poker game with Sergeants Provo and Lark and Mr. Beckworth.

You are perfectly correct about Watson surviving mission #2 by being with the first escape vehicle from the plantation.
