Nah, there is always more Intel to be gained. We've seen how Russia fares against those weapon systems and now it's a question of how will they change their strategy? If the US makes a prediction about new Russian doctrine, will the US assessment be accurate or does the US intelligence apparatus need to rethink it's analysis procedure. In a conflict heavy with drone usage, what can we learn about their use and more importantly, countermeasures, both on the adversarial side and blue side.

Anyway my point is that there is always more to learn from your opponent.
