I'm a little stuck... Click here to teach me more about this clue!

'military equipment' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'direct workers to overlook network' is the wordplay.
I cannot really understand how this works, but
'workers' could be 'men' (men can mean staff or employees) and 'men' is found in the answer.
'network' could be 'tissue' (I've seen this in another clue) and 'tissue' is located in the answer.
The remaining letters 'govern' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
