Imperial Guard was the second army I picked up for 40k. Back then (6-7 years ago) I wanted to make a horde army with loads of infantry men and heavy weapon teams. The IG vehicles weren't too appealing at the time. Since my 1500 lists included around 100 models
I decided I needed a quick way to paint them. So I needed a colours that were easy to paint on. Since I undercoat with black primer, this would be one of the colour. I guessed grey would be another colour easy to paint on and it would make a nice urban uniform.
To be honest I regret that decicion nowdays. I would prefer some brighter and more natural looking colours (greens and browns) but it's too late now and there is no use pondering the past.
I did some "research" recentrly and discovered that my colour scheme would fit nicely to the Cadian 122nd Regiment (I forgot to mention that I used Cadian models this far).
Ok my models didn't have the camo scheme on the fatigues but nevertheless it was pretty close.
Also I liked the colours on the vehicles.
I was sold for Cadia 122nd then!
