If CIC wants something done, they should order the SQUAD LEADER to do it. Outside of that, there’s not really much CIC can actually do.
CIC is more of a ‘relay information’ thing, where you provide info on the queen, location of hive and casualties, or things that need doing. If you aren’t providing call-outs on dead marines and other situations, you’re not doing your job.
That’s not to say CIC is incapable of directly herding marines- You absolutely can by ordering SLs specifically, the problem is that if the SL is bald or doesn’t listen, you’re basically shit outta luck outside of demotion for insub. I’ve seen countless occasions where even groundside COs struggle to herd marines because their SLs are bald motherfuckers who genuinely don’t care about the CoC- They’re just there to unga frag.
Squads follow orders and work together when the players in it actually want to. Much of the time, squad cohesion depends more on who is in your squad rather than how good the leader is. Leadership matters a lot of course- A good leader can get a large chunk of normally apathetic players to care and actually follow you into hell. But unfortunately, a good chunk of players just don’t give a shit, and never will. It’s not necessarily that they’re stupid, just that CM is a game, and not everyone will be as invested.
Personally, my biggest factor for whether I follow my SL is whether I know they’re competent or not. As superficial as it is (why not give all the unknowns a chance?), I’m a player, and if the satisfaction and fun I get from ungaing and holding LMB on 2D bug sprites is greater than the enjoyment I get from following someone on some fetch quest, I’m ultimately going to choose the option that I enjoy, unless I’m specifically bound to do so e.g. I’m in the unfortunate position of aSL and so must follow the bald XO’s orders as per roleplay rules.
You see this a lot when someone with sizable clout rolls up like fucking Windhealer, and then all the mute PFCs magically learn English and start praising their lord and saviour.
Likewise, if someone who I recognise as being actively responsive and who makes the round more interesting if I tag along, I’ll dive in hell and back for them, even if it’s some ridiculously stupid flank that’s obviously a terrible idea.
