I think it is a poor description. I recall having trouble with this one the first time round with my main account, I think I left it until I had upgraded a couple of HQ levels and had a larger troop capacity which made it do-able. When I came across it again with my secondary account I didn't mess about, I just used a load of jump trooper sample units to easily wipe out the base.
Note: in your question when you say 'did YOU just do a very poor job' are you assuming this forum is run by the game developers? For future reference this is not the case. This is a forum for players not developers so they won't be replying to you in this forum.
