A: *Sorry I couldn't come up with an answer for this one*
B: Their facial expressions show joy and happiness.
C: The soldiers were probably feeling nervous or frightened about going to war and leaving everyone behind.
D: I think the soldiers felt this way because they were going to have to leave their family and friends behind to go off to war. Also, I think that it was because going off to war was something risky and they could either win, lose, or die.
(Hope this helped! :)
