MGS 1 SPOILERS
Not exactly. During the Shadow Moses incident in Metal Gear Solid, you had Genome soldiers and ordinary soldiers who fought alongside Liquid. Genome soldiers are genetically enhanced soldiers through gene therapy. They are injected with Big Boss's soldier genes to increase their combat campabilities.
MGS 4 ACT 5 SPOILERS
Johnny is an ordinary soldier because if you remember in his conversation with Meryl in Act 5, you learn of his fear of needles. You also learn he has no nanomachines on him for this same reason too.
On a side note, in some ways I feel Raiden should die. The scene with him shielding Snake from Outer Haven would have been more meaningful. Not to mention it would have been a perfect allusion to Grey Fox's death. Then again Rose would have a bad ending if he did die.
