The Allies utilize high-powered lasers as weaponry. Infantry caught in the blast zone of a nuclear bomb or oil drum will run around on fire before falling down and skeletonizing.
The suicide bomb truck in the game has some lines alluding to their final fate, but nothing implies they feel suicidal rather than driven by their convictions.
The game includes other trained animals in military roles besides dogs, like giant squid, and dolphins, and those will be encountered as enemies. Whether to leave alone or kill wild animals or livestock is purely the player's choice. Some animals, like alligators, are hostile, though.
The USSR uses a nuclear missile as their superweapon. V-4's and Dreadnoughts are upgraded to tactical nukes at level 3. Demo Trucks, Crazy Ivan IFV's, and Terrorists explode into mushroom clouds.
