I returned my GS Viper set for the Amazon sale one. My other set came from Toysnowman so not much I can do there. I did get a good deal for Breaker off Toysnowman so it's fine with me.
Here's all my Vipers from the CI and the new 3 pack together.
With Python Patrol as well. I changed up some details on one to make him more an officer. I might get another PP Viper to make it one officer and 2 troopers if I get the chance.
I took one of my Vipers that has a white flesh tone neck but black arms and made him a Viper sniper using the Cobra Infantry head since that head portrays a darker skinned trooper.
My 4 BATs. I don't really recognize PP in my collection so I went with the plain black chest piece from the regular one. I might change my mind if I end up deciding to convert the battle damaged one back to not being damaged.
For fun, here's the OG13 I have so far from Classified line.
