In searching the 'net I found that the Japanese were experimenting with R4M type air to air rockets and panzerfaust air to ground rockets. I couldn't find a proper name for them, hence the generic designation.
As for other weapons mod packages I've done, the bombs and rockets are able to be lauched in salvos rather than the default one shot per weapon.
Any further info would be appreciated but not necessary.
