Looks like it's not easy. If you see the "TOE Up" column in the LCU Panel, you'll know when a unit's TOE gets upgraded.
I suppose I could add some window that shows the units using a TOE and/or show a TOE column in the LCU Panel... thoughts?
When I look at the LCU panel the earliest TOE Up is 376 days. I recall checking a few turns ago and it was similar. I've never seen text like,
Type/Mtn Brigade before either. It looks like LCUs are categorized in some way internally. Perhaps if the LCU panel had an indicator for units that have upgraded or maybe something in the Alerts panel on a per unit basis.
The Ship Upgrade panel is also very useful. Could something similar be done for LCU's?
I'm just throwing out ideas. No idea was is possible or difficult, or not.
