Honestly, it’s just silly that the Squadron OCU sits at a 0.3 lower BR, when it’s basically the same plane.
The only differences between the two are that the tech tree gets some better Air to Ground armament, and extra countermeasures, but you’d have to drop 2 missiles for those countermeasures, so they’re pretty much useless.
Either let the countermeasures be equipped with the 9Ms and 9Ls, giving the plane an actual advantage over the OCU, or move the tech tree version down to 12.7.
I suppose another solution would be moving the OCU up to 13.0, but the inconsistency between the two planes makes no sense in Air-RB. Really no reason not to do this, since the BR is already tested with the OCU, and it’s a really easy implementation.
