Hi, glad you enjoyed the clips, this particular work was to train a Univercity student in pyrotechnic practicle ( he got a first place), the models were all 1/6th scale, 2x Armortek and the one in the background that is destroyed in the second clip was a Mark 1 Tiger which has since been repaired and is now used as a hard target on our private range here in Cornwall.
The pyros are artillery simulators ranging from 12gms ,100grms and 250grms, which are detonated 500mm underground to give the impressive ejection debris with various other multiple strike devices in and around the vehicles. Hope this helps Phil for Magpies
