Question

why were viet cong forces constantly on the move during the vietnam war?
they did not trust the civilians around them.
they tried to avoid us troops and bombers.
they were afraid of being lured into ambushes.
they were unfamiliar with the jungle terrain.

Explanation:

The Viet Cong were a guerrilla force. The US had superior firepower, including troops and bombers. Moving constantly was a strategy to avoid being targeted by these superior forces. Civilians often supported the Viet Cong (so the first option is wrong). The Viet Cong were familiar with the terrain (so the fourth option is wrong). Avoiding ambush was more about setting them rather than fearing being lured (the third option is incorrect in this context).

Answer:

They tried to avoid US troops and bombers.
