Perhaps but like you said this is a failure of training, if they can’t see the value of enhanced operator-operator communication then more fool them. I’d be surprised to learn this though as experiences in JK should have given them sufficient exposure to that, NSG and SPG have had an operator communication policy for a while now
Plate carriers and badges seem to becoming quite common with NSG now, it seems also that they have increasingly abandoned the chest mounted pistol holsters for drop leg holsters (and hip too) but this trend of having the holster at the front of the thigh (I’ve seen it with Garuds and PARA SF too) just seems asinine and offers no benefits for some very obvious cons.
