Embrasures, how do they work?

[Guedez]

I was being raided by centipedes, and I've noticed that literally everything went right through my defenses like they were never there. This got me thinking, maybe this whole thing don't work like how I think it does.

After thinking about it, this is my theory why my pawns are now swiss cheese:

The red lines mean Protected, the green lines mean Not Protected
Is this how this works?

My new setup ( imgur.com/a/BYUJZOL ), works flawlessly. The corners are awkward, but it fended off a mechanoid invasion and nobody is wearing armor, nobody got wounds that may kill them.
For vanilla, you can replace the embrasures with sandbags, I don't think there is anything that would give the "melee can't reach you" aspect of this defenses though

Embrasures are like sandbags, but with better cover & you can't climb over them.

I don't know how sandbags work, exactly

[Koraxious]

Sandbags allow your colonists to shoot through them, while walls don't. If I recall correctly, since they are treated as a non-solid for you to shoot through, they have a ~65% chance to block incoming shots and absorb the full damage that would have hit your pawns instead. Basically, you can shoot through them and in exchange there's a chance you can get hit from external fire. Embrasures are functionally similar, but I believe embrasures have a higher % chance to block incoming fire. Which makes sense, given that sandbags could be stacked to approximately waist height, while embrasures are essentially walls with shooting ports in them.

You get behind a sandbag and have cover from ranged attacks that need to cross the sandbag to hit you (giving the shooter a lower hit probability) while yourself aren't impeded in your hit ability

[Majo]

Sandbag: Sit behind one, harder to hit by the enemy. Enemy can climb over sandbag, like a melee enemy can charge right into your face.
Embrasure: Sit behind one, even harder to hit by the enemy. Enemies can't climb over, immune to melee fighters if closed(Like a bunker).

Think of both as shields, Sandbags don't protect against melee rushes while Embrasures do protect.

[KalkiKrosah]

Embrasures are a hybrid of a sandbag and a wall. They protect better than sandbags but you can shoot through them unlike a wall. Embrasures are counted as a security fixture and as such should NOT be used in wall construction. Using them as a wall does not count as making the room an indoor room.

Since nobody's mentioned it yet... yes, you are correct in your assumption on how it works.

Embrasures (like any cover, so trees, sandbags, chunks, regular walls, et cetera) provide cover for pawns directly behind them. Unlike high cover (walls and doors) they aren't solid, so they do not stop bullets going in or out, but they do give a high chance of taking the bullet rather than your pawns. This chance decreases as the angle increases (so the more flanking a shot is, the less effective cover is) - so if an enemy were to fire from any of the green lines, your pawn (where the lines converge) would effectively have 0 cover from attacks from that direction.
