Rising Units: #11–15

These units are one strong week away from the top 10:

• Ghost Platoon
• 1st Battalion 9th Marines
• 1st Battalion 75th Ranger Regiment
• MDF PMC
• 2nd Battalion 6th Marines

How the rankings work

• Votes reset every day at midnight Eastern. A unit's rank depends on its members showing up daily, not on totals banked months ago.
• The weekly ranking adds up 7 days of votes, Friday through Thursday for this debut week.
• Anyone can vote once per day on any unit's page on MilSim Units.

Since everyone starts at zero each day, this ranking reflects how active and engaged a unit's community is right now. That's a better signal than member count when you're choosing a unit to join.
