Here is the story of the bazooka as taken from MOHAA site:
In response to the need for an infantry antitank weapon, Leslie A. Skinner and Edward G. Uhl of the Ordnance Department developed the bazooka-a metal tube that used an electrical firing mechanism-by early 1942. Until then American infantry had lacked an antitank rocket capable of stopping a tank.
Another member of the Ordnance Department, Henry H. Mohaupt, had been working on a shaped-charge grenade for use by infantry against tanks. Mohaupt's M10 grenade weighed over 3.5 pounds, making it nearly impossible to throw effectively. However, when Skinner and Uhl started attaching Mohaupt's grenades to their bazooka rocket, scoring hits on three successive shots during testing, the Ordnance Department immediately recognized the value of this new weapon.

Many bazookas were shipped to America's allies; in fact, when the Germans captured one, they copied the design to produce the Panzerschreck ("Tank Terror").

So here is the story:
The germans are entering a small allied camp to steal the bazooka, the allies are starting in the camp office, and the germans in the 2 gates. The allies have to prevent the germans from stealing the one of the bazookas located in the armory stores, by destroying their trucks (maybe tanks or jeeps?) using one of their bazookas located in the office.
So here is the question:
Will this make a good map?

storys dont mean much, have u read any of the storys on a map?

concentrate on the gameplay, u cant tell if a map will be good without starting it.

Exactly, TheNomad.
I dont care what the story is, I can be tasked with shooting down the hitler-baloon with my anti-aircraft pie launcher or stealing the V2 rocket plans from a secret underground complex, it doesnt matter. Gameplay > all that other stuff.

I'll just answer the question asked in the subject line

your map will only get as good as you make it. No better, no worse. a great story doesnt make your map not suck if you completely screwed up your gameplay or visuals. or both!
so put that stuff aside and worry about the things that count.

I just want to know if this sounds interesting or not!:D

No one cares unless you have fancy screenshots w/lens flares and hi-poly craters to back up your story with :P

Ok all try to build it, but i have to finish dod_training first!:D

everybody knows that the story isnt he most important thing... everybody knows that the number one important part of the map, that makes everybody want to download it, and get it on kustomkettle, to get heaps of people playing it for hours on end, isnt the story... its the name. :p
