On the security side, if you position yourself on a balcony on the right (-4392,23121,278), you can kill people coming out of spawn. A guy with an MG there is enough to decimate the team (picture 1). There is also bullet penetration in the walls protecting the spawn (picture 2)... Which leads to you being hit a few seconds after respawn.
Additionally, you can call fire support on the spawn or around, and I had the pleasure to die behind the walls protecting the spawn exit to a minigun support call.
TL;DR: this spawn is fucked.
P.S.: Fix the sound randomly cutting for the love of god
