How do you get the high-up powerups in mutant level of metal slug 2? - metal slug arcade games

I play Metal Slug 2 and level 5, a through the tunnel and kill the mutants. I noticed that putting the crew on the ground with red arrows pointing down and power-up in the ceiling. How do I get power-ups and there's nothing to do with a computer?
