Holy shit, had a mission where I had to destroy a relay and it was swarming with aliens. There was no way I could kill them all without some deaths or a complete squad wipe so I snuck around all the aliens and brought my squad up to a rooftop above the relay, blew a hole in it and started shooting the relay from above, where all hell broke loose. I thank RNG that nobody died, I had several squad members who were barely clinging on to life. I planted an evac point on the roof where my squad was, and got the hell out of there after blowing the relay up. An ADVENT trooper missed an overwatch shot, otherwise one of my best troops would have had a guaranteed death. I had to expose a couple of squad members to take that relay down, I'm amazed that nobody died, my back line did an amazing job at overwatching and doing serious damage to whoever climbed on the roof with me, so after weathering their attacks I could finish off a Muton and a Viper who were flanking our position. If that Viper dodged I would be so screwed lol
