Because if you've previously been reprimanded 3 times, on the 4th one you will be booted out of the army by the Colonel. Not very pleasant, is it?
Yet, there's a way to avoid this but you'll have to edit an internal OFP file to do it. The name of the file is 1985.SQC. You'll find it in the following location:
\OperationFlashpoint\Users\your_player_name\Saved\Tmp
If you have not played the campaign with OFP: Resistance version 1.75 or greater, you can use any text editor to update the 1985.SQC file. If, however, you have played the campaign with OFP: Resistance or greater, BIS has changed the internal format of campaign SQC files so that they are no longer editable.
Before editing the file, make a backup copy. Search for the last occurrence of the word "penalties". If you find this:
penalties[]={};
then you haven't been chewed out and you need make no changes. If, however, you find something like this:
penalties[]=
{
"Penalty01" (you may see "Penalty02" and "Penalty03" as well)
};
then replace the above lines with:
penalties[]={};
and save the modifications. If you're pestered by the Colonel again in the future, you may want to repeat this procedure to avoid ever being booted from the army.
