What is "Attack Pattern Shinzon Theta"?

Question

In Star Trek: Nemesis, Shinzon issues the command "Attack Pattern Shinzon Theta" during a volley of attacks against Picard in the Enterprise.

What exactly are the goals of the pattern and how was it executed?

Answer 1

It appears that this command is shorthand for "fly straight over the enemy vessel and shoot at them when you get close, while remaining cloaked".

Shinzon was gloating. "You're too slow, old man." He began punching commands directly into the control panel of his chair console. "Attack pattern Shinzon Theta."

He watched, a small, malevolent smile on his lips as the invisible Scimitar ran straight over the Enterprise, firing down on her at close range.

This tallies nicely with what we see on screen and what's in the screenplay.

INT. SCIMITAR - BRIDGE
SHINZON: You're too slow, old man.(entering commands in his chair console) Attack pattern Shinzon Theta.

EXT. THE RIFT - SPACE
The invisible Warbird makes a dramatic run straight over the Enterprise -- firing steadily down as it sweeps past it; is a brutal, close range assault --
