I would be tempted to use general reaction rolls for effects, modifying them by the effort.

Basically take the different groups in the army and assign the local different groups an effective reaction bonus/penalty then map the thing on the NPC reaction chart and use the corresponding %.

Basically reading the reaction chart it would seem that if it i known that abuse is not tolerated and that it is actually policed you can shift the thing from 9-: He may become hos tile if there is much profit in it, or little danger.
To 6-: acts against them if he can profit by doing so.

So on a +0 total reaction modifier it would go down from 37.50% to 9.25% for the affected troops. Different % values for different reaction modifiers but the end results on the table would be the same.

The effects of effort could use the indirect influence rules in social engineering p.61. Counting the troops used as military police(if they are themselves honest, that might require further campaigns) as money spent on the campaign with the other troops being the target audience. On success you would likely shift them from 9- to 6-, epic successes with skills as high as given for your PCs: likely a success by 10+ could shift the thing all the way to 3- and success by 20+ could give 0-
