@joebayles I think that this symbol should actually be a multi-layer marker symbol with two attribute driven symbol components/layers. How someone would draw the symbol would work like this:

1. User draws the symbol by clicking on the map at the centerpoint of the support by fire
2. User can rotate and scale the symbol depending on the size
3. User sets length of lateral support by fire line (attribute driven)
4. User sets angle of two fires arrows (attribute driven)

I don't think this is currently implementable in ArcGIS, but is definitely in the realm of possibility with symbol overrides, etc. Something to bring to both the SSMC and core.

@Dbarnes1 agreed, I guess I didn't really make my committee suggestion clear. Schema has to be updated.

@joebayles ideally these special case symbols can have UI where user enters angle/line length that isn't locked into our schema (Like how you can apply extrusion without it being in your schema), but we're definitely on the same page.

@joebayles if you are attending the next SSMC in person, this might be a good thing to discuss with the Army representative. If the angle of the arrows is doctrinally significant, the message standards can be updated. It takes a few years between the time a message standard is updated and the new version is implemented, tested, and fielded; in the mean time what you are implementing is very usable.

@ottenw - After discussing it at the committee, two things:
Suggest we only vary the length between points 1 and 2

Army rep will discuss with proponent agency.

This generated quite a bit of conversation. BLUF: This is a draw rule and implementation issue that affects several control measures and tactical mission tasks. The suggestion is that Army and Marine Corps will review and generate CPs to clarify guidance.

Esri should review control measures and ensure that the list is complete. Will open another issue for that.

According to the US Army, the only difference from the above graphic is that the angle between the arrows and the base line should be variable, though the length of the arrows should not be. The committee needs some help in deciding what the draw rule should like like, but in this case, it will still probably have to be 4 points. This will be the same for Attack by Fire, just with the one centered arrow, instead of two.
