Well, that's another argument.Level of training, quality of person, and equipment varies. You should know that. Would you compare a Navy Seal to a rank and file Private?
Seal, Ranger and SOF have extra training (I went thru Airborne School and Ranger School myself) so that of course is different than a 88M who just went thru Basic or maybe AIT. That is a different argument you are raising tho, you are saying they are Chechen or Militia so they are second rated. Well, it's like saying Army Reservist or a National Guard, who underwent the same Basic and AIT are any different than Regular Army or An Army private from Idaho who going to have the same training and AIT than a Puerto Rican or Guamanian would be different.
Or are you saying Russia are trained to a different regime than Chechen?
