Good responses. Some ideas:
- Giving marines a vague plan isn't great but it isn't a critical error. Marine movements have a momentum and like to follow the path of most resistance--they'll be led to the fight anyways.
- Failing to secure a corridor of evac forces you into an all-or-nothing strategy. Better to hedge your bets by securing it. I'd say you accurately assessed this.
- Giving squads some level of autonomy is good. Blind autonomy no. Moreover, information should continually be relayed. This facet of command is rarely the critical reason why an op was lost but is usually a major contributor.
- One of the most difficult decisions and leadership challenges faced in command is deciding whether to push or hold behind cades, and determining how you can get your marines to actually follow through. This is the fundamental skill and determines if your CO is good or bad.
- Being blind to chokepoints and flanks is a a critical error. You accurately assessed this.
I hope I catch you in a game so I can see you first-hand, but I doubt it'd change my opinion. +1
