Global Combine Squads
Automatically applies any spawned combine NPC such as soldiers, metropolice, hunters to the same squad.
Squads in Source allow you to group NPCs in ways they understand. Members of a squad will cover each other, move together, share information, and take turns attacking their enemies. However, they have limitations:
Squads cannot be directly influenced in the regular ways that individual NPCs can be. The mapper can still influence the individual squad members.
Squads will not stay together if directed otherwise by a scripted or semi-scripted sequence.
There are squad leaders, but unlike in GoldSrc, they don’t influence the squad in any substantial way.
Squads can contain no more than 16 members.
Only two soldiers in a squad can attack at a time, so large squads may be highly ineffective.
Please note that this hinders attacks from large group of NPCs and may instead of improving combat will actually make it worse in some instances.
