How to Deploy Shields, Cades, and use Medic Boxes?

[Swadius]

At it's very core, all you need to do is click with the medic box and dep shield out. There are however, a ton of things that can go wrong that stop this from happening. The most reliable way (though still pretty unreliable) is to either be looking straight up or straight down when you click. Not having anything immediately in humping distance in front of you will also help immensely.
