When I attack an enemy, their health bar has a blinking white portion when I aim at them.
At first I thought this indicated the possible damage from an attack, but as you can see from this screenshot, a 3-4 dmg grenade is highlighting slightly over 6 bars of the enemy's health, and I can attest that it only did 3 damage to the enemy in question.
What do these blinking white health bars mean?
This is the maximum damage of the attack, minus the armour of the enemy. I am pretty sure no other damage sources are taken into consideration (e.g. a tank that is guaranteed to explode).
This mechanic is somewhat bugged. You will notice that in certain scenarios the blinking does not stop, even if an other target is chosen, or if an other attack is done first. What you are seeing is likely the potential damage for a different attack.
