On another note the only thing preventing the U.S. from having an army of Supersoldiers even after Erskine's death was an incomplete understanding of what the serum had done to Steve. It wasn't until after he was thawed out in the present that it was discovered that the SSS had both made him a universal donor and that anyone who received a blood transfusion from him became a Supersoldier too. See Diamondback. If they had known back in the day they could have had Steve give a transfusion to a volunteer then wait for Steve and the volunteer to recover, and you would have two supersoldiers. Then have both of them transfuse two more volunteers making four, then four becomes eight, etc. In a year they could have had thousands of supersoldiers ready to fight.
