A tactical wank is one where you manage to slip away in an awkward or boring situation to masturbate in a quick time frame and manage to get back without anyone noticing that you had gone away. Further more people must not have knowledge of what has just taken place. A more informal slang term for this is "tac wank"
Example 1.

*R slips back hoping no one has notices his absence*

"Dude, we know that look, you have just been for a tactical wank haven't you."

Example 2.

"Where have you been son, we were having an important dinner discussion about poor university grades?"

*cough* No where, I just needed a minute."
