Loved this issue. It really showed the Joes as being very intelligent as they defeat Cobra without firing a single actual shot.
It also featured the very first mention of Springfield.
And let's not forget all of Cobra's undercover operations, which are quite impressive. I believe this was the first time they were featured extensively (from the spies catching info about the MOBAT to two different portions of the parade being ran by Cobra agents to being able to construct a command center right under the generals' parade seats).

Character-wise, we got a good treat, with Cobra Commander being completely unscrupulous, and Flagg being the "good guy", not even taking a shot at CC despite his flawless aim, on the .0000001% chance that he MIGHT hit an innocent bystander.

The issue wasn't dumbed down for kids, either. After Flagg gets shot, Cobra Commander flees as girl scouts look on...
"Look Susie! That man shot the soldier and is running away!"
"Don't worry, Julie! They'll catch him! They always catch the bad guys!"
And Flagg, hearing this, simply whispers to himself "I wish that were true, little girl..."

And G, General Austin doesn't appear in this issue. He's mentionned by Steeler at the beginning, and Flagg sends him a memo, but he's never seen.
