Strike Force Heroes 2:
Hard Challenge #8: Bring Juggernaut with balanced armor, or maybe General with Automatic Weapons passive skill to avoid the need o constant clicking. You have to capture 2 flags, then just sit waving your weapon until time passes to gather points. There are several problems though: 1) the enemy has a team, while you are alone. This makes holding, or even capturing two flags hard. 2) protecting the middle flag is suicide. 3) you can't reflect flamethrowers, most rockets/granades, and the bullets are not reflected back to your attacker directly, so there is a HUGH Real Life Factor for this. Suggested passive: Reflect bullets. Crouching makes enemy hit you even less.
#9: You have to be agressive. For this you need the RLF for meeting enemies. At many times you simply can't encounter anyone, and those times no matter how pro you feel, you'll loose. The only good news is, that the Point Leader (the only AI which will gather points enough for victory) will lickely kill itself a couple of times with bazookas and more often flamethrowers. That's your chance to gain advantage. As your armor will be shot down fast, I suggest bringing only balanced armor. Might worth trying armor against explosion+elemental damage too. Class is definitely Juggernaut for extended health.
#10: very easy at last. The AI is stupid, don't go after you, just pass a predetermined route. Go the rugged platform, and crouch in the small tunnel on its right. Check the radar. Wheneber you see a red dot on the rugged platform - shoot. If you run out of bullets (you will after a lot of kills) come out and let them kill you to refill your ammo (I don't think there's an ammo-spawn at this map).
#11: most frustrating this mission is. You get points two way: you shoot the burning man, or you kill someone while you yourself burn. In theory the next burning man is, who shoots the burning man. Except when the guy manages to kill itself, then the burning man is random. So you must gain points by kill the burning one, then die by the hand of someone else then the Point Leader, what is bloodly hgard to determine when everyone is doing 1HKO from out of screen.
#14: depends on Real Life Luck. Reroll the level until the enemy has low armor, bad weapon setup, then watch out who is the AI-nominee, and steal kills from it, as well as let the other kill you when you are low on HP, ammo, or such.
#15: you have to gain advantage at the early period, else they'll outshoot you with that sniper rifle and whatnot. I found it most effective if you stand below the bottom left platform and w8 until they jump down from it, or crouch on the upper left platform blindshooting down-right. These r the safest position I found.

Campaign:
#1: stupid little gun you have. Don't even think about going melee. the only advantage you can get is health and armor, so bring your best setup for that. Play cooperative defensive: your team won't do your job, but they aren't too bad either, so always try to go in pair with one, using it as meatshield, killing from behind the guy. You're max lvl anyway, so you don't need the kills for yourself.
#5: play defensive. Capture 2 flags by your team, then just sit tight on one as long as possible.
#6: play DEFENSIVE. Your team will do the job sooner or later if they outgun (random weaponry u know) the others, but they sux defending your bag. So push ahead when and how much possible, but remember that your top priority is protecting your base. But if you see them all running away where you can't reach the, - go give it a try and try to steal their luggage!
