In order to decrease the number of casualties and limit the number of potentially dangerous situations that Soldiers encounter, the US military is exploring the use of autonomous Unmanned Aircraft Systems (UAS) to fulfill air support requests (ASR) from the field.

In this paper we present the development of an interface that that allows the user to plan an ASR using sketch and other inputs while conforming to the user's mental model of natural interaction.
