The U.S. Army Rangers, arguably a "light" infantry force, defines it as such:
"A raid is a combat operation to attack a position of installation followed by a planned withdrawal. Squads do not conduct raids. The sequence of platoon actions for a raid is similar to those for an ambush. Additionally, the assault element of the platoon may have to conduct a breach of an obstacle. It may have additional tasks to perform on the objective; for example, demolition of fixed facilities."
The U.S. Marines have a pretty slick manual devoted entirely to raids, MCWP 3-43.1
Historically, when World War Two began to go badly for the Japanese, they lost control of the air and sea and their own artillery could not hope to match the increasingly overwhelming firepower of the Allies. The raid became an often-used tactic in an attempt to compensate for their own lack of firepower. While many small raids were successful, they could do nothing to turn the inevitable tide of the war.
Still, it is always good to look at the tactics of other nations, to see what went right and what went wrong, to learn lessons, and to pick up little things not covered in American manuals which could be of use.
