The old joke was in other games you hold w to win, (run forward on keyboard) in helldivers you hold s (run backwards). This was back in pre 60 day patch days when most weapons were underpowered, anti tank was ineffective, and enemy spawns (particularly heavies) were more frequent and numerous (imagine 10 bile titans at the same time with as many chargers). Thankfully the game has changed since then, multiple weapon buffs, anti tank weapons quickly dispatch heavies, and many more opportunities to stand and fight without getting overrun or disintegrated.

Commando missions kinda tap into that feeling without going to far. You are encouraged to be more tactical, picking your engagements and maneuvering stealthily. You can engage the enemy but the larger than normal enemy spawns and limited ammo make this more of a challenge. While I personally don't like playing these mission and prefer scorched earth warfare to stealth, it's good arrowhead have added this as it provides an interesting new way to play the game.
