The unit icon is positioned over a single squad member. This can cause issues for people who click the icons to issue commands to the squad. The biggest issue being unable to retreat.

See....when the icon is over a single model and that model dies, the unit icon shifts. When your units are dying quickly and you want to retreat, the icon can move several times causing you to miss clicks.

I love to see it adjusted to be the way it was in coh1 and coh2 where the icon is centered between the squad members and that would resolve this issue.
