Second day of uploads, starting it with something simple yet I believe very crucial to Bosco's backstory. This was done by my ever talented friend Falopaxy.

15th interceptor squadron, the "winged sentinels" or "Sentinelas alados", are Bosco's former unit, their mission is to defend and ensure their nation's sovereignty over the skies above from any and all invaders. Bosco joins the unit not long after returning from Europe, becoming the leader given his experience overseas and his familiarity with the recently acquired Spitfires that the squadron would fly, replacing the old biplanes that were too long in the tooth.

The unit insignia features the newly acquired planes flying above a stone tower, sporting the national colors in the background.
