No offence, but the order markers seem to have some wrong symbols?
All Ahead Full, Lock on and Brace for Impact are nice and clear.
And I get 'Full stop' instead of burn retros, that works.
But why is Come to New heading the recycling symbol? Or is that meant to be Reload Ordnance?
And what is that Flag? It's obviously either new heading or reload, but doesn't really represent either intuitively?
My recommendation would be an Arrow describing an S curve for CtnH and a row of three bullets with a + symbol for reload.
The blast markers are neat though
