The whole of Shadow Company was on lockdown, no one got in or out. Training and missions were cancelled all because of a horrible flu that got spread around.

Even the Commander, Phillip Graves was sick and off duty. It wasn't the worst thing to happen, it was somewhat entertaining watching everyone walks round in very casual and comfortable clothing and it was nice to get a break.

The major downside, besides illness, was being trapped inside the base with nothing to do.
