What is the minimum essential information to pass if full BDA cannot be briefed?

The minimum essential information to pass when full Battle Damage Assessment (BDA) cannot be briefed is focusing on "good effects, damage, and time." This encapsulates the fundamental aspects necessary for determining the effectiveness of a strike.

The term "good effects" refers to the observable outcomes of the strike, indicating whether the munition hit its intended target and produced the desired impact. "Damage" quantifies the extent of the destruction or degradation inflicted upon the target, providing insight into operational success. Lastly, "time" signifies when the assessment was made, which is critical for understanding the immediacy of the reported impacts and for planning subsequent operations or reactions.

Together, these elements provide a quick yet comprehensive overview of the results of an engagement, which is vital for decision-makers to assess the situation and plan further actions if needed. While assessing other aspects like success rate or simply stating the end of the mission may have their merits, they lack the vital combination of impact assessment that is crucial in this context.
