Does completing the side-mission Lock and Load have any in-game effect?

Handsome Jack mentions that if you get some loaders to the moonshot that "they'll join you on the moon's surface."

Does this actually have an in game effect, and if it does is it affected by the number of loaders that survive?

Solution 1:

I don't recall ever seeing any loaders on the surface as a result of this mission.

The fandom wiki doesn't say anything about it, either.

So, no.
