From manufacturers website:
British infantry have the Bulldog and Deadly attributes that improve their determination to win assaults and their lethality while they do so, making them really good up close. Meanwhile, their tanks have the Fight Another Dayattribute which reflects their past bad experiences and unwillingness to hang around in a losing situation. This attribute reduces their Last Stand rating, making them more likely to cut and run if they take heavy casualties. Although this makes them a little fragile when things go wrong, it does let you field a few more tanks with the points discount, hopefully allowing you to avoid the whole going wrong thing in the first place.
