The easiest way, IMO, is to go with either
wolves of steel megamod, or
wolves from the deep magui megamod. Both are an "one step" awesome multi-mods package.The difference is mostly on graphic layout ( look on youtube for the difference), but both will give you a real good immersion and realism. When you are ready, there's also a version of Wolves of steel with real nav.
