Which they will if they don't want to come under AA fire.
Well, that's the question: Which is worse? AA fire, or wildlife? Or, how close do you get to the AA before it starts getting too accurate? How many days march through the wildlife is too much? Where's the sweet spot in-between?
They're Abominites - even if they know that we know their plans they'll still follow them.
Again with the assumption that our enemies are stupid. Perhaps it's correct, but I'd hate to be the guy who underestimates his enemy.
Let's think for a moment here. If we manage to kill a lot of the escorts, and the enemy realises that we are anticipating their movements, what are they likely to do then?
Keep the rest of the fleet closer to the transports? They're already in "tight formation around the transports". I suppose they might stray less from the transports to provide orbital support, that seems natural and likely enough.
And when attacking our defence stations they'll have to either leave transports behind, leaving them more vulnerable to our fleet, or take them with the fleet into the grinder, leaving them vulnerable to our orbitals. They'll probably go with whichever is the lesser evil.
But what else might they do?
Simplify their plans? I don't know how much simpler their game plan can get: Escort transports to Avernus, escort back to Valinor, repeat while enduring constant ambushes.
If they
attack elsewhere they get to split our fleet and armies up, at the cost of splitting up their own forces, but they'll have to deal with less of Ridcully's precognition out of system and no wildlife. But I wonder if that would leave enough of their forces left to even get through the Avernus city walls. This might actually lower the attrition on their fleet, allowing them to stay in the fight longer. Of course, this strategic issue is far more complicated than can be summed up in a single (grammatically proper) paragraph.
Maybe they can just sacrifice a few more million of their citizens to
have the transports possessed by Angyls. But they probably would have done so already if that was an option.
So far, I'm thinking the best idea for the enemy is to split their attack as soon as the Avernite orbital defences have been removed. Ridcully can't be everywhere. But I'm probably overlooking some other options. What would you guys do if we were playing Abomination Polity Quest?
