No knock tactics vs. "military" operations.
Military Operations Urban Terrain [MOUT] tactics differs significantly in several ways from no-knock entry tactics.
Consider
In MOUT, methods of breaching may use kinds of force with little regard to human life on the other side. Shoulder fired missiles for instance.
No knock has the ability to use shaped charges but use a battering ram when they aren’t actually kicking the door. I can imagine what some folks would say if LE actually blew down a door. OMG!
Following breaching, the MOUT team may deploy a fragmentation grenade or a flash/bang at a minimum into any space if they so much as "suspect" a hostile within.
No knock teams use flash bangs as a distraction at a maximum only in targeted areas.
MOUT breaching teams may not be as concerned with target identification as with target acquisition.
No knock emphasizes target identification.
Utilizing enhanced NVGs, MOUT nighttime entries are preferred over daytime usually around 0200 local. OBL for example.
No knocks that use daytime are likely to lose the element of surprise.
MOUT rarely knows the floorplan of the structure they are clearing.
No knocks may not know the specifics, but there is usually a working knowledge of a floor plan.
It’s usually shoot first in MOUT. Very little "negotiation" takes place. Occasionally you might hear a MOUT team member holler "DROP THE WEAPON!" in whatever dialect, but this usually draws unnecessary and unwanted attention from other sectors.
No knock make entry encouraging dialog by first verbally announcing their presence and giving verbal orders to the occupants. They talk first.
No knock are bound by the US Constitution.
MOUT is bound by the Geneva Convention Rules of War.
One more thing. When our Reserve and Guard SWAT guys headed off to get their MOUT training prior to deployment, it was clear to us the military was heavily dependent on our training and adopted tactics from their civilian counterparts ... probably none more so than LAPD SWAT because up till we started kicking doors in Iraq, no one had better training in forced entry than US law enforcement. Better AND safer, I might add.
No google links to give you. Just personal observations FWIW.
