Toad as a Warrant Officer
So, we see by his insignia that Toad is a warrant officer; except, throughout the film, he is treated like a PFC. Somehow, I get the feeling that nobody involved with this understood what a warrant officer is. They are technical experts who are put in a leadership position. It's a common rank in the helo world. I suspect that they essentially wrote him as a PFC and then a technical adviser said he would be a warrant, based on his job; but, no one took any further advice about his role within his unit. When he's chastised for being in officer's country; well, he is an officer! It's an officer rank and carries the authority of one. When he's chewed out by Delroy Lindo; he would be addressed as "sir." He wouldn't be on latrine duty. Well, the CO could order it; but, he'd lose the respect of everyone in the command, especially the senior sergeants. Granted, this guy was a poor leader; but even bad ones know where to draw the line.
Fortunately, Ah keep mah feathers numbered for just such an emergency!
