I don't think it was authorised, but common enough, to select reverse pitch on RAAF Caribous before touchdown during Vietnam war. To minimise risk from ground fire, a steep approach was often needed. For maximum protection, the touchdown point was also planned past the end of the strip, and any misjudgement could result in excess energy and insufficient length remaining.
Close to ground, select reverse idle, check actually achieved (2 blue lights), select max reverse power and full back stick as power applied to prevent nose gear damage.
I have witnessed one stuck in forward and max power applied on both without waiting to check the blue lights. Of course it was a short and very narrow strip. A STOL landing could often be completed in the length of the aircraft, but high and fast, one in forward meant it was a difficult touchdown and landing roll. A previous post refers.
Don't try this at home!
