Well...
If you look at the details... it gives the measurements. the Sherman is 18" long, 14" wide, Tamiya's is 14" wide, 7.2" wide, but I'm guessing thats the BOX, not the tank.
According to the [link=http://www.forcesofvalor.com/series.aspx?series_id=2]Forces of Valor site[/link], all the R/C units are 1/24. It lists the same 8 tracked armor vehicles on the Sears.ca site (search Forces of Valor at
www.Sears.ca)
I couldn't find a listing for the Brit 57mm AT gun or the German PAK 40 75mm AT gun, but I'm betting they are 1/24 like the tanks.
Yep, did a Google, found one on Kijiji in Toronto, both AT guns are 1/24.
Sorry guys.
