I won't cover clearing rooms within rooms in this post in case there's a muj scanning dbz sites for cqb tactics , but the gist of it is as follows.
First off, you have a 5-man team (as per the vid). Generally, when you first make entry into a room, you want 6-8 dudes. Whatever, you have surprise on your side and provided you maintain speed and violence of action, you should be good to go. Unless there's a mounted .50 cal aimed right at the entrance. That's why this first part is the most important. Before you make entry, you don't dilly dally your way up to the door. Here's a pic of the general setup of the building minus the stairs and the rooms to the right.
Moving on.
As you can see in the pic, there's an inward opening door that opens to the right. Easy peazy. This isn't how I'd do it, but for the sake of instruction, here's how we were taught in baby school. You'd stack up on the door, one behind the other. That's 5 men in a line. Now, that's stupid because of the way the building is situated, and there's a fence with a dog behind it, meaning people could potentially make their way back there and merc the lot of you before you even make entrance. Whatever. Bear with me. We crawl before we take cities.
Before I go on, let me just make it clear this is going to be room clearing as if you had 300 more buildings to check after this. There's the long clear, and there's the expedited clear. The long clear involves a lot of logistical crap, and lots of comm between you, snipers and DMs and your leadership. That's not what you do when you're assaulting a city. That's what you do after you've already captured it and you think Baghdad Bob is in the building and you want him.
Step 1: 1-man is going to move to the right side of the door. He isn't going to run past it. He isn't going to roll over to it. He's going to briskly walk to the other side while covering the door with his primary. Why? If someone shoots an AK at the door, there's no guarantee he's going to get hit, so if he doesn't, he's going to want to throw a little suppression their way. Why walk? Anything else is unnecessary and loud. Surprise. Maintain it while you can.
Step 2: In the vid, the dude basically shoulder charges the door, and then automatically becomes 1-man. In reality, this probably just got his entire squad killed. So that's a no-go. 1-man, the one who walked to the other side of the door has just become 2-man. Why? Because he's opening the door. Now, whether or not you're 1-man, 2-man or 3-man depends on your position in relation to the door, and what kind of door it is (inward opening/outward opening to the left/right, etc). In this scenario, 1-man just became 2-man, and 2-man is now 1-man. The guy behind 2-man is 3-man.
Why?
First off, it's faster this way. Secondly, once that door is open, 2-man has the most depth on the room. That means he can see more than the 3-man, and probably slightly more than the 1-man depending on his position in relation to the room (proximity to the walls, L-shapes, hallways, etc).
Step 3: The new 2-man (Red), gives 1-man a head nod to see if he's ready. 1-man responds in kind. 2-man turns the nob slowly to make sure it isn't locked. If it is, it can go 1 of 2 ways. Either 1-man can donkey kick it, turning 2-man into 1-man, and letting the rest of the stack flow by the original 1-man (the one donkey kicking), or donkey kicker can flow in right after 1-man enters. I'd rather everyone flow right by him because he's going to turn to his right after kicking the door, forcing him to basically do a 360 if he wants to get right back in, slowing down the op.
We're pretending the door was open. 1-man walks in at a brisk pace, because you want to move only as fast as you can engage. We aren't the army. Someone shoots a single round, there better be a single casualty. None of that FULLY AUTO SPRRRRRAAAAAAAAAAYYYYYYY bull****. If we were going to do that, we'd have just called in a JDAM.
Anyway, 1-man gets in there, 2-man follows immediately afterwards. Immediately. There is no hesitation. He walks in, and pins the door the wall. If it rides flush against the wall, he moves on into the stack. If there's a gap big enough for a person, time to clear that ***** out (Clearing the door, gents. Word? Word. Open the door with your rifle under your armpit and prepare for danger. Why under your armpit? Because at that distance, you're not missing your target. Also, if it's under your armpit, the muzzle is that much farther away from potential enemies, making it awfully difficult for them to grab it, pull it to their side while its still slung to your body, and knifing you under the chin. )
Wonderful. We're in.
Step 4: Depending on the size of the hallway (my picture is hardly representative of the building's actual dimensions), you'll determine what kind of stack you want to move into. Since there's enough room for 2 men to stand shoulder to shoulder, and then some, we move into a split stack. That's just two stacks on either side of hallway. They move up and see an L-Shape. Wonderful.
Right side of the hallway has the most depth on the left side of the L-shape. Both sides move up until they're cut off by the imaginary line that stretches from the right stack's side of the wall, to the end of the left side's side of the wall. Fantastic job! This is taking way longer than I anticipated, so I'm done drawing pictures.
Left side decides to do a high-low. That's one man standing, one man kneeling, providing double the firepower should an enemy appear on the wall closest to them going down the L-shape. The 1-man on the right side is going to walk his way down his side of the wall until he's on the other side of the room/L-shape. While he's doing this, he'll be scanning and providing security while 1-man/2-man of left stack clear their side of the room, visually. Once 1-man from right stack hits the wall, his stack meets up with him, and left stack prepares to clear out the rest of the room. This means looking behind furniture and all that.
Furniture is cleared out pretty much the same way you'd clear a room. You don't just walk up to it and say clear. You have someone providing security for you, and you either clear it on your own, or simultaneously with a buddy. Why? If you go down, your buddy needs to take the other guy out. This saves lives. You're the canary. It sucks, and you have a 70% chance of getting schwacked as the 1-man, but its a fun gig.
Since the whole L-shape thing looks a little confusing in text, I'll draw one last picture.
And this is just a giant empty room. Add furniture, **** up the lighting, throw in a stairway, add extra rooms, blah blah. It sounds like a lot, but it usually takes maybe 5-10 minutes for initial sweep of a decent sized floor. If there were multiple floors, you'd go in with multiple squads and try to take it all down simultaneously.
Anyway, I'm not expecting them to clear every goddamn nook and cranny. Just make entry correctly. Medal of Honor had it the closest so far.
