They look like American M60 Main battle tank. The one to the left has a bore sighted battle field illuminator. I was looking at one of those lights for sale in Texas, guy wanted $350 American. Shipping killed the deal though. Light weighs 260lbs.
It has a 3 mile range and will put a quarter mile circle of light at 2 miles. Full adjustable focus just like a mag light with a hand held control module.
24 volt 140amps with 156 amp over drive. Xenon short arc bulb. Included an IR lens.
I was going to mount it in the bed of the Deuce with a home made tripod.
And yes those are some nice tanks. Still used today.
