Do flamers do friendly damage?

[infraRed]

Does flamer turret flame do any damage to friendly units? In the thick of battle, it seems like this might be happening, but it is difficult to tell.

No they don't. Which is pretty strange. I'm not sure if they do damage to allied units which are not yours; anyway, this damage will be caused by units moving through the burning ground, not by the flame burst itself, which is also pretty strange, that is, when units are on a burning ground but don't move, they don't get hurt.

All friendly units are impervious to the incendiary radius which is 50% of ordinary flamer and 85% when you come to inferno. You still can be hit by mistake and suffer from direct hit. It WILL happen a lot since the flamers are all grouped together and have a bad accuracy (50%). But the direct damage is negligible vs the incendiary puddle of death you make for enemies units when you start to focus your fire like that.
