The word "maneuvres" implies that that there is still some engine
"after the third rocket motor" has separated.

The earlier missiles, about which I read, had their last engine separated
shortly after launch. The reason of this is simple: they try to use
as much of the payload which goes to the space as possible for the
warheard(s). Everything else (as much as possible) they want to separate
on the early stages.

But the warheads of "individual guidance", are
guided when they re-enter. Perhaps the later
missiles use Cel Nav also on this stage.

Alex.
