Yes, Battlefield 1942 (while having pretty good graphics), doesn't even try to be realistic as far a gun penetrations and armor penetration resistance. It simply a "capture the flag" free-for-all with a WWII setting only for effect. Call of Duty and Brothers in Arms do a better job (still not realistic when it comes to armor, though). The best games I've found are a little old now, the Combat Mission series. Now these guys got absolutely anal about getting the armor penetrations/reloading rates/line-of-sites perfect (love those Brits and their attention to detail). Supposedly a newer redone version is coming where the infantry looks as good as the tanks.
