I think it depends on the context of the situation. Steve always strikes me as a get the job done kinda guy, (most men I've known who were in the military and actual combat do) so if he were speaking in a time/place/situation where Pidgin gets the job done better than standard English, he would. But if it's striking you as "off", then you may be on to something. You can always try a rewrite, taking out one or two references till it feels more natural.
