So, is the whole game so annoyingly hard? It basically gave me 4 men and a vehicle to crush an unending hordes of enemies, that can basically destroy all I have at their convenience. I'm just ranting around, don't mind me too much

You can pick up a few more men from the trenches before you go to the tank. You can then use these men to pick up any vacant anti tank guns which comes in useful when you head north from the town. You can also loot corpses for ammo and bandages and your tank's tracks can be repaired as many times as is necessary.

But yes, the game is a... little tricky. But the mission after that one is bloody awesome. You have to complete the first, even if for no other reason than to play that one too.

Some MoW missions are squad level and pretty frustrating.

Others (like the second mission) are insanely chaotic affairs where you control an entire army.

And then there are the stealth missions, which will make you scream in frustration (then jump for joy when you win).

It has stealth missions!? Damn you, impulsive buying!

Don't fret! If you can think before you act, you'll be fine. ALWAYS watch your enemy's patrol paths, never attack with everyone in the same area at once, and ALWAYS make decisions in the heat of battle at the right time. (For example, if you hear the sounds of a tank moving in, find cover and unleash unholy hell from above with 'nades until everyone is dead around you.}
And besides, the stealth ones are the hardest ones. =)

Pretty much all of that Rohan stated.

Men of War is kind of rough.. I think it's actually a step back in terms of refinement from Soldiers: Heroes of World War 2. The friendly AI needs a lot of babysitting as they are completely hopeless once the bullets start flying. Great game and all, but not an improvement on Soldiers, unfortunately.
