If you look at a loaded weapon in the inventory screen, you can see the damage statistic. It will say xxx + yyy. That 'yyy' is the bonus from your enemy skill. Average enemy skill gives +0%, lower than average gives a penalty, Super Heroic give approximately +80% damage. For example, my super heroic leader's XMB does 280 + 224 dmg/rnd. A soldier with Very Good and an XMB deals only 280+74 dmg/rnd. Sadly the leader bonus to improve the damage of nearby soldiers seems to not work at all. A soldier with Very Good enemy skill will still only deal 280+74 dmg/rnd with the Super Heroic leader around. Knowing this, I'm thinking prioritizing Enemy over actual Gunsmanship skills is a good idea.
Planned out my group build for a Super Human playthrough. Expected my level 2 leader with super heroic Enemy skill to turn my team into destruction incarnate with that juicy +80% damage bonus. Instead I'm seeing no change. Is this a known bug or am I misunderstanding/misusing the leader bonus? I can see the "Soldier gets bonus to Enemy skill" on the portrait of the other soldiers. On a related note, does the special Psionic equipment work right? I'm a few days off from getting it and I was planning on making an entirely psionic team to utilize all of those nice bonuses. It would be a bummer if they turn out not to be working either.
