A: Yes but only for various reasons

A: Yes but only for various reasons. If an enemy is attacking you and you go into a building they will attack and destroy that building or structure to get at you. And if you build a very tall stacked structure and think you can hide up high you are wrong. The enemies are smart and will attack the primary support of the structure. Once that is destroyed everything else will fall, along with you!

Also, if you die and then respawn near your Uplink while enemies are present they will attack and destroy it to remove that ability. So make sure you protect your Uplink!
