In Godsend, the Allied Shield Commands projected force shields onto nearby targets.
It would interesting to have Shield Commands project a miniature force shield or defensive buff around itself when Force Shield is activated.
And just to make it uniform for all Allied subfactions, Mercury Uplinks could have their own bonuses when you build multiple. I can't really think of any good examples, but I'll throw a random one out, each Uplink gives a bonus mercury strike charge up to maximum of 3.
