I went for a very similar concept, very stamp oriented :) Great execution overall; I see some people mentioned this, but I think that giving the player some feedback would have allowed some more engagement as well.
Feedback in the form of stronger animations on the casualty counter, to give the player some feeling that they made a mistake, or the right choice, or feedback in the form of instructions indicating what they did wrong (e.g., inform the player they flagged something as verified when false, because they failed to check the signature, or the platoon number).
Great job to the both of you!
