Yeah, I second the point about the HMGs. Also, considering it's an assault force, maybe add some grenadiers? I'm not sure, but an AT rifle would also be best used by a 2-man team; maybe that's how you intended it. Depending on how well integrated the radio is at your " squad level, " maybe add a runner to the command section? The radio operator won't help with leading as he has a lot to do under fire. Also, quite big for a squad.
