This is not a permanent redeployment, but this is how SLBP deals
with its lack of NAC buses, due to NAC buses being MIA... 
i.e. 1894G, 7236S, 7269Y, 7271P, 7280M, etc
So firstly, SLBP will pull in the 154 NAC buses to deploy on those
permanently NAC JIS svcs (and 179 x-over to 255).
If not enough bus, they will pull in more VO2x from PAC 192 and 193
to deploy on JIS.
SLBP has lots of SP ADD, but they won't be deployed on 192/193!

So, again, SLBP pulls in Mercs from 154 and 242 to deploy on 192
and 193, replacing those VO2x.
Then finally, SLBP will place the SP ADDs on 154 and 242!
