Observations: I believe Predatory is a must on Alpha Bridge builds, it gives just enough sustentability to make it a pretty good build. You'll be able to spam Tactical Link plenty of times during a mission.
The primary weapon I use outside of taclink, determined will help get tac again asap. The secondary one whenever tac is active so commanding will keep it alive as long as possible.
The Damage to Elites Firearms mods are a good help here, but if you'd prefer you can use some Firearms Mods with skill haste on them.
