🇧🇬 Bulgaria
A 37-hour MilSim on a former military unit near Bosnek, at the foot of Vitosha – a newer series running several operations a year.
ATLAS MilSim runs its games on the territory of the military unit south-west of the village of Bosnek, Pernik municipality, with a total duration of about 37 hours. ‘ATLAS MilSim by Blackthorn’ (1–3 August 2025) started on Friday evening and ended on Sunday at noon, with 178 players responding.
Since then the series has continued with named operations such as ‘Saber’ (April 2026) and ‘TRIDENT’ (18–20 September 2026), keeping the same weekend format from Friday night to Sunday noon.
Bosnek, Pernik is about 30 km from Sofia as the crow flies. An easy drive for Bulgarian teams – car-share with your squad, as parking near the game area is usually limited. Always check the organiser’s rules on replica transport, FPS/joule limits and tickets on the official channels before you book.
