Squick: The description of the mutated baby being born and dying, among other things.
Nightmare Fuel: The description of a young girl, burned beyond all recognition by the explosions, only recognisable as female because of the jewellery fused to her body. She is described as trying to speak, but all that comes out of her mouth is "phlegm and teeth".
The description of the Cadet running home to his family only for a bomb to go off above his head. His scalp is graphically described burning off, his eyes and skin melt, his "teeth burst", until he is left as a skeleton, which immediately disintegrates after being hit by a nuclear blast-wave.
