What does this excerpt tell you about the nature of

the fighting in Vietnam?

The communist forces lacked heavy weapons

like artillery.

American troops withdrew easily by

helicopter

US troops had to move and fight the enemy

on the ground.

O Fighting stopped during the night so each

side could recover.

DONE

I think it's that US troops had to move and fight the enemy troops on the ground.

(I can't see the except, but I know this of the Vietnam War) (the forestry was too dense for accurate positioning, so US troops had to fight the communist forces in guerrilla warfare on the ground)

I hope this is right!

The answer is C!
