Surplus Zone: PIAT EOD Training Bomb

Whilst looking through the piles of surplus ‘kit’ in my friends warehouse in Germany I came across an interesting find, an Explosive Ordnance Disposal (EOD) training kit that has several examples of WWII and after ordnance that might be found on training grounds and former battlefields throughout Europe.

One of the elements from that training kit was a PIAT or Projector, Infantry, Anti-Tank, round. Many of these have been found across northwest Europe since the end of WWII and it was important for EOD teams to be able to identify them and understand how they work in order to safely dispose of them.

This example is likely an ‘instructional’ round that may have been produced from a previously live round and not subsequently marked as inert. In the video, which was filmed on location from memory, I mentioned that the charge was inside the front cone. Instead the charge was actually just behind the steel cone, which acted as a forcing cone, and has seen been replaced by some sawdust. We can see this in the diagram below, which shows an earlier Mk round but the configuration remains the same:

This time we examine an example of the Mk3 PIAT Bomb. When I filmed the video I wasn’t sure of the markings but this chart below more clearly explains them:

There were 7 marks of PIAT bomb:

MkI yellow/green/yellow band 808 stamped on green band, red x’s around nose cone

Mk2 as above

Mk3 yellow/blue/yellow band TNT stamped on blue band, red circle around nose cone

Mk4 as above

Inert bomb black with yellow band INERT in white

Drill bomb black with DRILL in white x 2

Practice bomb – to fit the practice insert tray, painted white and it looks nothing at all like a PIAT bomb!

Our inert bomb isn’t painted black, instead it is painted up as a Mk3 to emulate what a live blind found in the field would look like.

Here’s an extract from the PIAT’s manual explaining how the fuze was fitted to a live round:

From the PIAT manual:
The fuze. – Until required for use the fuze is kept in a container attached to the drum tail by a spring clip….

ii. To fuze. – Remove the fuze container from the drum tail and take out the fuze. Remove the thimble from the bomb nose by pressing it downwards and turning it clockwise. Remove the transit plug from the fuze chamber and insert the fuze flat end first. Replace the thimble. The transit plug should be placed in the fuze container and the latter put in the carrier, in case the bomb should later have to be unfuzed.
