My team uses Canadian DPM. The Canadian Airborne Regiment was the only unit in the world that used the pattern, now we have dona an homage to that unit. We have made custon helmet covers and boonies to go with our uniforms. We are immensely proud of our uniform and the pattern. It seems to work in a whole lot of different terrain.
I own several different types of camouflage (because I'm a kit whore) and I try to keep everything as "issued kit" only (i.e. no reproduction kit).
As Peter mentioned, for games our team goes out in CF OD's and Canadian DPM. For skrims though, I normally attend in CADPAT TW.
This is what I have currently:
CADPAT TW (Temperate Woodland)
CADPAT AR (Arid Region)
CF OD (Olive Drab)
CF Tan (first Canadian desert uniform)
CF Black (my only repro item)
British S95 Temperate DPM
British S95 Desert DPM
Dutch DPM
US Woodland (currently modeled as LAPD SWAT)
German Flecktarn
Australian AusCam (just the shirt, working on pants)
Various UN Blue items
I'm still working on getting Polish camouflage, US Army ACU, black tactical crewsuit for a SWAT motif, and possibly contractor apparel.
At the moment I have in my wardrobe these ones:
-Bekas in Gorod/City
-Flora BDU with VDV modification and patch
-Splav Gorka
-Sposn Sumrak
