The question itself is flawed because all armies after Alexander emulated his tactics and therefore Caesar would have been familiar with them. I voted for Roman.

Propably the Greeks were influenced by Assyrian siege tactics, but as major sieges prove, the Greeks did posess some expertise in siege engineering. Troy would be an arguable example, but Thebes, Halicarnassus, Tyrus, Gaza, or the sieges in Central Asia (all under Alexander) show that Alexander very well knew what he was doing.
