I see this in lots of scripts, sometimes right after a Destroy(e).

Many thanks.

It activates the entity you set in the "if used" field. It doesn't do anything if you don't set the 'if used' field.
It doesn't need to come after 'destroy'. In scripts like 'plrinzone.lua' it has no purpose when 'if used' is not set. I think it's added to scripts like 'plrinzone.lua' so that people can use the 'if used' field without the need to edit any scripts.

Right now it is used to spawn hidden objects by putting their "name" in the "ifused" field in question.

The most common usage being to place a bunch of soldiers and set them to "spawn at start = no" and then put the name of said soldiers in the ifused field of a trigger zone to make them appear when the player enters that zone (they must all be named the same)
