Well-ell, you need SH4 v1.5 with FotRSU on it then... You'll see them ash cans light-up and cause all sorts of mayhem, even getting thrown into other ships and lighting them up! I cannot remember if Stock SH4 v1.5 does that or not... I've got both here, and I'll see if there's a setting in the Depth Charge's sim file...
