I've found fairly consistently that AI ranged units are not penalised by range/terrain/LOS the same way the player is.

In this image, the 3 archer units at the top were all able to shoot my Cav at the bottom.

I thought I'd see if anyone else has noticed this before I lodge it as a bug.

That should be working as intended. If the unit is 2 elevation levels higher than the intended target, they ignore line of sight penalties. Archers also have indirect fire and can fire over obstacles like hills and mountains (which I find a bit odd but it is what it is).

This same elevation rule helps direct fire units like crossbowmen fire over your units as well.

Hmm, I'll take a better look at unit traits, etc next time. I just know I struggle with LOS, etc at times and these guys shooting over mountains was confusing.

LOS for ranged units: every possible enemy target has a red circle on its tile if the ranged unit can attack it. This is also shown if you want to move the unit to a particular tile. So you can see beforehand if any and which units can be attacked.

Hey lads,

Melliores and Shakee, thank you for your answers. As they have stated, this is working as intended per the characteristics of the archer unit.

We have noticed some confusion and struggles around the LoS since the release, and although I can say that improving LoS rules and feedback is in our backlog, I cannot promise that it will be done in the next few patches.

Cheers everyone :)

Archer has indirect-fire trait. It working as intended but yea, you would be in disbelief that they can shoot over the mountain to hit your cav.
