Hello, I'm having some trouble with this mission as well.
I sold off some buildings and made a bunch of IFVs and put tanya in one, I went as fast as possible to the base in the southwest and destroyed it as soon as it spawned, I kept the GI's on a cliff near the start to slow down the soviets and sent the grizzlies to destroy the tech lab.
For some reason though, even though I pretty much annihilate the conyard as soon as it spawns, I don't get the victory noise for achieving a secondary objective. Is there some hidden building somewhere?
Do I have to interact with the tents in some way to progress? I'm kinda stuck here because tanya is in the pool, the tech lab is destroyed and there is no trace of anything at all of the southwest base. I destroyed the sentry guns at the start of the bridge too.
Edit: I decided to just wipe the entire map and wait for the southwest base to finish building then went ahead and killed it, and it worked.
Additionally, I am playing the campaign on hard and it is quite fun and inventive, I think the only thing I dislike is the trucks dropping crates that are mini-nukes, that seemed a bit cheap because even if you avoid all the crates, you can no longer save as the client will encounter some error. So you have to do the whole thing in one go which can be annoying when there is a constant supply of trucks that are not auto-targeted by your units.
