Description:
This type of entry is slower, but
safer for less experienced or less aggressive
entry teams.
Operator 1 and 2 take up positions of cover on
either side of the opening and scan the room
from outside using
limitet entry technique.
Shooting is done from cover/concealment.
When they are satisfied the room is “safe”. They
make entry to either side of the opening, by
using crossover. They don’t follow the wall, but
enter and use the path that they have cleared
(2-4 steps so they don’t over penetrate the
room). To make sure that there isn’t any
furniture blocking the way, and if there is an
enemy in the corner, the operator don’t move
strait in to his line of fire but slightly
across it.
If the opening is big, it is possible to use
buttonhook.
When operator 1 and 2 have cleared the corners
operator 3 and 4 can move in to the room to the
left and right of the opening, and provide
additional firepower.

Pros:
- The team clears most of the room with out
entering.
Cons:
-It takes much practice to time the movement so
that it is fast but the operators don’t bump in
to each other.
-The operators can be exposed for crossfire from
each others weapons.
-Team is compromised
after opening the door with out entering.
