Sniper is an interesting military themed figure. Decked out in green camo, Sniper would fit into any Joe squad. As Power Commando figures go, he's actually kind of boring. The whole point of this series was outlandish figures. And, Sniper doesn't fit with that. But, as he's unique to the line, he does provide a nice juxtaposition from the more off beat characters.
Sound Speed is the more interesting of the two figures. He's obviously based on the Cobra Eel mold. But, instead of flippers, he appears to have skis and ski poles. I'm not sure why. But, his gear makes as much sense as rocket skates or a Mummy Man who also appear in this line.
There are both green and black versions of the Power Commando weapons. This pack is different in that Sniper includes black weapons while Sound Speed has green accessories. You see that the weapons are recycled molds from the earlier series and remain the kitbashed version of G.I. Joe weapons.
