The Laotian Civil War is little known, but when it was done, the nation was the most bombed per square kilometer in history.

It also adversely affected the NVA operations in South Vietnam and prevented them from staging aircraft from Laos to support its forces in South Vietnam as they instead had to use them to help the Pathet Lao.

It also consumed the majority of their Armor Forces preventing them from being used in the South in large numbers till late in the war.
