It depends which era or conflict your doing aircraft from. But WW2 the invasion stripes where applied to aircraft for D-Day to aid allied aircraft recognition.
FAA aircraft also applied them during the Korean conflict, and again during the Suez crisis when they were yellow and black stripes.
A quiet check on the net, asking for images of your choosen aircraft will probably provide evidence of whether stripes were applied, or checking the squadron history could be another avenue? Hope this helps!
