I remember that particular missile launcher building (#303) being part of recycled animation in a whole lot of episodes, but there weren't any battleship-style gun turrets like those seen in 1.0 as far as I recall.
UrsusArctos: Yes, it is recycled quite a bit. I looked through the series and movie and realized they always show that building 303.
Funny detail: Even though the fortress city got wiped out near the end of the series, in The End of Evangelion we see building 303 again, still standing. NERV attempts to utilize it to resist the assault of the UN aerial forces.
...and my dear building 303 is completely useless.
I thought it was useless against Angels, but seeing it be useless against the UN forces just breaks my heart.
