Yes the 50 Cal machine gun is included..I have not "detailed" my tank yet with it and THe really great place for accessories is Back Yard Armor aka "BYA" www.backyardarmor.com
If you want to "battle" you will need a Tamiya Battle Unit...BYA has these...all prices from BYA include shipping
You need paint, glue, and of course a 4 Channel Ground Frequency Radio and also a 6 Cell Battery for the Tank and charger...
I HIGHLY recommend a 3300 mah Battery as these will give you well over 1.5 hours run time on it... Plenty for battling...I usually go through 1-2 packs per meeting/Battle Day without having to worry about having to recharge more batteries while there..
Keep your questins coming...We are glad to help///
Last note GET BEARINGS as I did...BIG difference btw my SHerman and a Stock SHermans wheels in ease of rotation... Just my observation at the Sunday meeting I rolled a stock Shermans wheels and then mine....Big difference...
