Ok, after an hour or so of tweaking:
I can tell him to fire the flashbang, and then I get the targeting recticle, and I tell him to fire at the ground or something. He runs up to being in range, but once he gets there he runs in place while firing and keeps running in place until it's reloaded, fires, etc. I want it to be that once he fires he goes back to normal weapons, like the comanche's rocket pods. What's worse, after he's fired his flashbang, the the next ranger I build is in flashbang mode too. I could just leave the flasbang code as it is, but when he switches back to primary mode he wont use his secondary(long range version of primary,) he just runs up to the range of his primary and fires it.
