The RC sapper is an AIPlayer, thus you cannot by standard give it it's own built-in name.
You can, however, do something like this:
// %rc is the RC Sapper
%rc.shapeCam = new Camera()
{
datablock = Observer;
rcSapper = %rc;
};
missionCleanup.add( %rc.shapeCam );
%rc.shapeCam.setMode( "Corpse", %rc );
%rc.shapeCam.setShapeName( "whatever" );
Make sure to remove %rc.shapeCam when the RC Sapper is removed.
