The Talent Summary Screen gives a summary of all the Talents a merc has. This screen can be pulled up from the Talents tab in the Barracks or during a mission by double-clicking the merc in the Turn Timeline.
Each Talent is presented with a description of the current effects including any applied upgrades. The Action Points required to activate are listed on the right along with the cooldown time. On the left is an icon for the Talent. Under the icon, pips indicate the number of charges the merc has for the Talent.
