It's all public domain stuff chaps, we might as well as 'fess up to what we've got. It's only sporting to give whirling dervishes out in the sand half a chance.
At great expense the J has been equipped with the following defensive aids:
Basic Armour
Very thick paint. In places.
Extra thick cushions for the pilots.
Dark sunglasses. Very dark.
IR defences
Loadmaster in para-door flicking matches off edge of matchbox
(certain aircraft have been upgraded with the GE doing similar from the other door)
LIRCM - handheld laser pointer. Requires steady hand. And spare batteries.
Radar countermeasures
Foil meal trays flung from escape hatch. Torn up if we get enough notice.
I think I've said enough
