Item description for Vtg Photograph 1930s Soldier Posing With Tank Armored Vehicle M1 Or M2 Maybe

Came from an album of photos of soldiers of the 2nd field artillery at the fort Clayton Canal Zone in Panama. Not sure the exact location of this photo or the name of this piece of equipment. It looks like a tank to me, but now sure

Always happy to answer any questions if I can.We will combine shipping, especially on small items it cost the same to send multiples as it does to ship one.
