I have Schwann's blessing to add this

From the extended description; "While a common sight in the Alliance's more rebellious or devastated worlds such as Mars, the Army peacekeeper beret became a potent symbol of Sol's triumph in the civil war. Nowhere else in the Spur are the blue berets more omnipresent than the former capital of the Restoration Front - Lycoris."

Available in the headgear tab- I've put it as an independent item since the beret selection is for departmental / non factional berets, if desired, I can move it under there.
