M90 worn by Swedish soldiers:
Photos taken at the Swedish Army museum in Stockholm, depicting "future Swedish soldier":
The M90 uniform system is called FU90 (Fältuniform 90 = Field uniform 90), so the designation of the different uniforms is FU90P, FU90K, FU90L etc. (but I suppose most people call them M90P, M90K etc.)
FU90P = for personnel in armoured vehicles, has a different cut FU90H = for helicopter crews - the inside is bright orange FU90K = the desert version (öken means desert in Swedish - I don't know where they get the "K" from...) FU90L = lightweight version of the M90, "L" means something like "lätt" (light)
Only the FU90K is in the desert pattern - the others are in the "green" pattern.
