Seller says this is a WW2 photo. I don't recognize the uniform of the man so I don't know for sure.
Which AC is that on the left - a White? Where they used in battle in WW2 or rather in other roles, or is this more likely a captured arsenal? No connection to the seller. Regards, Pat

Your right, the AC is definitively a White. A french Segur and L armored body fitted on an american truck base. Those AC enter in service at the very end of the WW1 and remain in use until the WW2. But most of the vehicle was refitted using a french Laffly base, and this vehicle had not been modernised. Maybe a pic taken on a army workshop or depot.
