Next to the stats of the selected unit and its Commander, the "General" tab displays the Logbook. This contains short messages of the key moment in a unit's carreer, providing information such as date of commision, destruction and reforming or changes in the unit's Commander.
The "Statistics" tab provides more detailed information about the unit's combat performance. It lists the damage and kills done split per unit class, as well as a summary of its overall performance.
Love that Stats for Damage/Kills, when playing PC you can see that a unit that does most of the job can only count 10% of the kills but the recon unit that i use to finish them take all the kills
