Why'd you change it?
Because it was a bit much to already have kevlar on the suit.
Also, a vaccine is quickly made (It takes less then 6 months to create a vaccine for the flu I mean really) and tested on an Aribissian woman. The vaccine seems to have worked, and it is now being mass produced and divided among towns and cities.
blazer, 500 of your soldiers have died from your arrogance.
I'm going to reduce this, seeing as
A) The respiratory systems, like Miko said they were, are not for radioactive materials. They are to keep unwanted substances out of the lungs,
such as radioactive dust and debris.
B) Soldiers barely have any interaction with citizens.
C) Soldiers wear gloves. Given that this won't stop the virus all of the time, I offer a compromise of 100 soldier deaths, and 678 civilian deaths.
