Yes, to the north of Delta are the remaining Daisies including their Light Anti-Armor troops with cannon, and to the east of it on the flank (and therefore south west of Bravo) are the two Mindies.
As for what can be seen at this time, the Daisies are intermittent contacts that come in and out of weapons-lock; they're vulnerable when firing or having just fired, in addition to when they've just been struck. Which is why High-Ex is important.
The two Mindy armors however, are flat out different.
You can get a decent heading and location read on them at all times so long as their Aether Tap and Combined Field Systems are functioning, and a very good one when their weapons are active (firing). And of course, the weapons locks would be just as good when their shields are being hit or just been hit. Despite the easy lock however, they're just plain UFOs in the way they move - the hit that Lisa got earlier was only due to the fact that they were in a hurry to hit Delta, not Bravo. If they're on their toes, they can flat out dodge or shoot them down. On top of this however, they can 'go dark' just like the Daisy and simply run off their capacitors like they did earlier, eschewing protection, firepower and mobility for stealth. The degree to which they can do this is not a yes or no either, as the one giving Wulfe a little notice on his sensors before accidentally running into him is a clear example - her propulsion was still on, but the rest was off. And, fortunately, if they're dodging missiles, they'll have a harder time dodging shots too.
For now though, the two Mindies are decent weapons locks.
In order for the missiles to work reliably in all cases where armors are using stealth features, you'll have to 'light them up' by hitting their shields and creating a defensive reaction before firing during the short window afterwards. Otherwise, their ability to seek will be hampered. Additionally, if you can't confirm a kill, don't assume that it is. On top of that, the enemy can salvage weapons from each other too.
Do note that they're down to 5 from 7 in terms of Daisies however.
And, now that I think of it, I may just need to write down a damn combat guide for this style I'm doing it in.
