Corner positioning & partial cover?

Not common in my meta, but yes, it looks to me like cover from both opponents.

 

I use it all the time. Maybe not all minis, but at least a few times per game.

 

yep - I see this often and use it myself

 

Somebody better at geometry than me should be able to calculate the length of the wall required to claim cover based on the model positioned directly at the apex of the 90 degree corner is all troopers are S2.

In this example if the blue is active green probably shouldn't claim cover because Blue only needs to deviate a few mm out from the wall to gain a position that ignores the cover.

 

Tactically used often, no
Accidentally used often, yes.

 

Edit: Ignore my reply.

 

Tangentially on topic.

Basic Rules state that in order to have line of fire you must be able to see a minimum of 3mm x 3mm

"The Trooper must be able to see part of the volume of its target, with a minimum size of 3x3mm."

Does this mean that the silhouette must protrude a barrier at least 3mm or can you spread that area the total height of the miniature? so does a 40mm by .25mm sliver exceed the minimum 3mmx3mm because the area is greater?

 

You need to see a 3x3 square, though only one trooper has to see a 3x3 square off the other and then LoF becomes reciprocal, so you can have 3x3 square to a sliver of silhouette and both troopers will get LoF.

 

Can you draw a "special LoF" from troopers backside or are prone snipers on rooftops with their butts turned towards the enemy still untouchable during reactive turn?

 

Drawing LOF and using it are two different issues. To draw an LOF, you only need a LOF to exist from one trooper to 3x3mm on the other trooper, and this makes that LOF reciprocal. To use the LOF, you need any part of the enemy inside your LOF arc.

And yes, I am aware that the rules suck at using proper game terminology to explain this.

 

In my opinion the RAW and RAI about LoF are pretty clear. Prone snipers with their butts turned towards the enemy are untouchable.
However, this is so stupid on so many levels that players have come up with an let’s say creative interpretation that makes those troopers targetable.

 

@paddyBatman yes, that is what the rules clearly say but not how people actually play because it’s ripe for stupid abuse.
