Where can I find the "survivor of the old war" in XCOM 2?

In XCOM 2, one of the preorder bonuses is that you "Instantly unlock a survivor of the old war as a recruit in your barracks." Apparently after they are recruited, you get access to a new cosmetic armour. I preordered the game but I'm not sure where this person is or if I have already recruited them. Does anyone know how to find this person and what the unlock actually is?

Solution 1:

The survivor of the old war is simply a regular, normal recruit, but wearing an XCOM Enemy Unknown outfit. This is based of a developer's tweet here:

The soldier has a randomized name, will be equipped with "Resistance Warrior Kevlar Armor", and will have a unique bio, e.g.:

A survivor of the old war, Min Ho was a ranking officer within X-Com when the organization fell. He is rumored to have survived the ill-fated pre-war X-Com operation later referred to as the "Kiryu-Kai Disaster".
