Yi it does not matter if I can be trusted.
yes there is service shaft in the tunnels that would have been
boody trapped too.
Got a solution to that puzzle. The key is turn back to ancient
teaching - the use of water !!!
Let see with the enemy in position and fully booby trapped . There
is not way you can disarm them and charged them in that tunnel
without being effectively stopped in momentum by them somewhere
along the tunnel before the MRT train.
What we need is something that move very fast moving and have power
to move ahead to take out everything including booby trap and enemy
in the tunnel all the way to open the way right to the MRT and
create a few second of delay. The element is water !!!
Use water !!! Build a huge huge huge container of water, then
release it suddenly, a sudden gush of water like tidal wave down
the tunnel which water force will take out all booby traps and
claremores and all armed enemy outside the train. The MRT due to
its weight and size will not be affected. What ever NVG, the bad
guy see the tidal wave only, not the vehicle and SOF behind and
smoke will wash away by water.
Its effect also created the few second which is needed freeze the
enemy inside the MRT. Then the SOF then can follow behind the water
in a vehicle right up to the MRT and charge !!!
May sound like a crazy ideal but it will work beautifully.
Of course air pressure can be consider, but think water is the
safer option.
