Offering would be great, but there are other honor guards, also - the SO has one, for example, as does KSP. But yes, the offer should be made, but even if not needed, nothing prevents officers from going except the lack of desire to go. I don't expect everyone to go, but it would be nice to have a decent showing, especially given that it isn't that far. Farthest I've gone is Olive Hill and Somerset, for funerals.
