I sure remember both the T-flash and the arty sim. Here in Australa, they have pyro too, but its pathetic compaired to the ole arty sim.
Here a t flash is called a wizz bag, and its about 1/10th of a t flash. As for arty sims, they just whistle here, and thats all. No flash and bang.
However they do have a good variety of simulators on the BESS (Battlefield Effects Simulation System) a purpose built electrically fired multi function system.
We have have a thing which is called a SPAL, like a mini-mortar electrically fired, and disposable. Out comes a platic bomb filled with MOGAS, and about 10 metres in the air it explodes. Nice and wet. One can hook mup a host of sims such as mortar, arty, small arms fire burst, and single shot, etc.
Last Sep/Oct I went on a DMEO/BES/BESS course at the old School of Military Engineering, Steel Barracks, Assault Pioneer Section, which strangly falls under the School of Infantry now. It was a **** good course, as the last time I had done a similar course was back in 1991.
Also Detcord, CE primers and 600g slabs of TNT are also used in BES (Battlefield Effects Simulation) which is different from BESS. BES is very effective, and realistic.
The CF have used similar if I remember right. All BES is never electrically fired, but the use of M700, detcord and generic non-electric blasting caps are used.
