The alternate ending of the movie takes place right when Frank get's infected. And the military isn't even in the final part of the film.

After Frank gets infected, Jim knocks him out with a baseball bat and they tie up frand with rops and put him in the car. The roadblock was actually blocking the road to the Cambridge Primate Research facility where the infection first spread.

After investigating the inside of the labratory Jim finds a doctor who has locked himself in a room. Jim asks the doctor for help and what they can do to save Frank. And what spectre said the studio decided not to put it in because a full body blood transfusion sounds retarded.

All it was, was story boards and Danny Boyle commentating.

HAHAHAHAHAHAHA I love the part where MAYLA vomits blood in the soldiers face.
