Currently myself running Stoker with the Stark AR, Sawbones with a SMG-9, and my 3rd merc changes to much to say, normally my filler spot for other merc’s that need to be played for missions or what ever im feeling for a map as a mess around merc.
Current Merc squad, and favorite loadout!
I’m running Logitech Aura card BL81 Classic Operative (gotta buy a better loadout tbh), silver S62 Modern Rifleman Stoker and bronze BL32 Standard Operative Fletcher.
Sparks 383, Kira with a variety of loadouts, and an open slot for mission mercs. For kira, I’m swapping between b41, b83, and s81 – I’m leaning towards the br-16, but I’m not sure which loadout I like.
My fragment G75 Redeye stays in the squad at all times, second slot is usually nader/proxy/sparks depending on the third slot, which is there for any mercs I have a current mission for, along with either Vassili or Kira if I don’t have a merc mission active.
Mine changes all the time, variety being the spice of life an all that.
But I do have some specific mercs for specific maps and game modes that i must take with me.
Execution
- Stoker
- Sawbonez
- Open Slot (Normally Fragger/Redeye)
Stopwatch
Underground
- Aura
- Open Slot (Normally Proxy)
- Open Slot (Normally Fletcher)
- Occasionally take out Fragger, Nader in place of either Proxy or Fletcher depending on what mood I am in.
Bridge
- Fragger
- Aura
- Open Slot, Love to take Red-eye but often go for an ammo carrier for the last bit on defense as I have no idea what mercs the other guys will bring and actually use
Chapel

Terminal

Objective
Anything as I don’t know what side ill be on, wish I could know in advance so i could choose my mercs accordingly or better yet if there was a squad selection option which you could configure in the menu so you would have your preferred squad for the team/map you are on without ever needing to worry about “if i was on defense i would take proxy but since i don’t know ill go with vasilli” (never happens but just an example xD)
Solid blue cr83 cobalt nader with spares quick draw enigma : weapons : crotzni , selbstadt , cricket bat.
Urban black bl32 silver fletcher with lock on quick draw springy : weapons : blishlok , empire 9 , stilnotto stiletto
Urban black k92 silver fragger with cool tough engima : weapons : k121 s&w.40 stilnotto stiletto
As you can see i really like explosives 
Edit: Fixed a typo
The lineup:
Fletcher, because he’s an explosive engineer who’s damage per second rivals fragger at times.
Sparks, because she can snipe and be a medic: basically a multi-class on her own.
Skyhammer (or RedEye or Phantom; I want him to be decent one day.), because everything besides spotting and ammo-giving were covered with the first two mercs: why would one need anyone else?
