I think it would add a bit more realism if the markers placed by squad leaders / commander looked hand drawn, because when a squad member hits tab to check his hand held map instead of looking at a computer (as an insurgent at least)... you need to imagine he writes these locations down on his own is if they were magically relayed to him
The markers should look hand drawn and not so uniform..
Keep in mind, these markers are being written without a table and these people aren't artists... so they could be messy.
