Different ways to airbrush an urban/grey tank?

[nismogrendel]

I'm getting ready to paint one of my Leman Russ tanks.  I like the light grey urban tank look.  I don't think I want to do a camo pattern at all on this tank.

 

I've found two different tutorials for painting a Russ in this style.

 

 

This youtube vid says to base the model black, spray center of panels light grey, then go over the entire panel lightly with the same color:

 

 

This BOLS post starts with Mechanicus Standard Grey, hits the top half with Dawnstone at a 45 degree, then hits the top of the model with Administratum Grey.

Both styles then go on to weather the tank in various ways.

 

 

Are there any other example styles I should be looking at?  Anyone have examples of their own urban/grey tanks?
