ai_goal_assault is a point entity available in all 
Source games.
This entity specifies which NPCs are to carry out an assault, and triggers it when any conditions given are met. One goal can handle multiple rally points. Must be active to be able to be triggered.
Upon activation, the entity will round up all its actors (specified in a keyvalue), and instruct them to select their assault_rallypoint(s) and move to it/them. Upon arrival at the rally point(s), each actor then begins waiting for an Assault Cue, unless instructed to assault immediately.
Upon the cue, it will then instruct all actors to begin moving on from their current rally point to the assault_assaultpoint specified by the rally point.

Inputs
BeginAssault- If the entity is active and this entity's Assault Cue keyvalue is set to Entity System Input, begin the assault.
Tip:This will cause NPCs to "skip over" the rally point if they aren't there already. Useful for using rally points for selecting actors.
AI_GoalEntity:
Activate- Make the goal active if it wasn't already. NPCs will begin taking orders.
Deactivate- Make goal inactive.
UpdateActors!FGD- Tell the goal entity to re-check Actor(s) to affect in case any disappeared, or any new NPCs spawned.[confirm]
