It's not in 4-5 moves, but maybe this could work
Also I think It's 2300+ puzzle

The first move is Rxm6+, and regardless of what green plays, it's a forced mate in 4-5 moves. Blue doesn't have that many options to defend anyway. The only piece that can prolong mate is the rook, and once it is lost, it's game over.
