if I were a bettin' man, Id say you got a .zip (or a bunch of .zip's) and just saved 'em to the maps folder. if it's just one zip then youre in luck. you should be able to just open the .zip, select
every folder in it (should be like 3 or so folders: maps, scenery, textures), do CTRL+C or right-click and hit "copy", then go back to your Soldat folder (like C:\Program Files\Soldat or wherever youre game folder is), do CTRL+V or right-click and hit "paste", then click "yes to all" when it asks if you'd like to overwrite existing blah (it should. otherwise you didnt put them in the right place). run soldat and see if it worked. if not lemme know. if it did work, then maybeh +1 karma would be nice?
