Only to a certain amount but it does Varies on what Tank it is, How much Armor it has got and where. All Tanks should usually take normal gun bullets but when it omes to tcank shells, it only takes a certain bullet depending on the tank to destroy another tank.
e.g. During WW2, The Soviets built the IS-1 Tank to defeat the German Panther and Tiger Tank, which the IS-1 had a 122mm, It was just capable to destroy the German Tiger Tank but required few direct blank shot hits due it's 120mm Armor. So as a response to the IS-1, The Germans brought out the King Tiger Tank which it had at best of 180MM of Armor. The King Tiger had 88mm Highly Explosive Gun.
So Tanks are only bullet proof if the ammo hitting the tank doesn't damage or most importantly penetrate the Tank Armor.
