Disabling run for Infantry units?

[Freelancer Tex]

Hi,
Just like some artillery units,I want to disable the double time for the line infantry units. I have watched some tables,but I wasn't able to find a value/attribute/or something else to disable the run for the infantry units. I have tried to activate the attribute "Slow_Moving" but it doesn't work.
Any Idea?
Thanks.

there is a column in units_stats_lands_tables called "is slow moving"
infantry units have the entry "False". change it to "True" and they wont be able to run.
the column is in the last quarter of the table.

Thanks for your answer.
But as I said before:

Maybe there is something else. How did they do that with artillery?
