What am I?

Answer 1

Answer:

It's the Russian T-34 model 1942 medium tank

My shield is thin, yet the shape makes it thick.

The T-34 tanks were well known about their armour. They had a thin armour, but the engineers used a good angle (sloped armour), and the incoming projectiles often bounced off the tank.

I guess this is a reference of the German panzers. Hitler's tanks usually had a nickname like "Tiger" or "Panther". These tanks were well engineered and were great opponents of the Allies' tanks.

I have so many teammates, while few of them do communicates.

Not all T-34 tanks had proper radio systems – especially the early versions – so communicating with teammates was hard. "A lack of properly installed and shielded radios – if they existed at all – ...".

There were more versions of T tanks manufactured by the soviets which could be the "winner" of this riddle; but the T-34 model 1942 had two hatches, making it look like Mickey Mouse. Reference: "These can be identified by their hexagonal turrets and the open twin “Mickey Mouse ears” hatches."
