Hi all
Those rockets can be fired either singly(one per pod per trigger pull) or ripple-fired (a stream of rockets per trigger pull) or salvoed (the lot are fired off at once...very inaccurate because their multiple slipstreams throw off each other's aim).They could be the same kind used on American aircraft such as the Apache and Cobra.These rockets are an improvement on the old SNEB/MATRA 68mm rounds because they have a higher velocity are are more accurate....As for the photograph of the entire armament fit, such kind have been taken for every armed aircraft in the Corps, at one time or another.
