Architecture of Half-Life 2: #131 Combine in my Launch Tube HD

The White Forest base gets invaded by some combine. A bit of combat in and around the secondary launch tube. I think the rockets are a bit small. A quick search of Wikipedia found the Titan II ICBM, which looks just like the rockets here. The Titan II is 33.53 metres in height and 3.05 metres in diameter, which makes them about 1.5 times the size of the ones in game.
