Steve, it sounds like you are preaching that a Striker Company makes Tank companies obsolete.
Now, I dont really think thats what you are saying, but it might seem like it. Also, seems like the Tank company in your scenario lives in a vacume, which I dont think it would do.
My scanrio could be: Stryker Company on advance, runs into tank ambush = one dead Stryker Company. These scenarios do not tell much about te eabililties of the units as they are fictional and would seldom, if ever happen IRL.
