Hello Schörgi,
for the moment, in the team, we only use smoke grenade and nothing else.
Why ?
Because each player must, at first, learn the individuals and the collectives technics. And if you use "accessorys" a little too soon it can be prejudicial for the progress, and the final level, of the "student".
And for the moment we don't have the collective standard to use claymore.
For that, a good motto is : "chaque chose en son temps" !
N.B :
Concerning your socks be careful. Because, sometime, smell of these clothes can be considered as biologicals weapons
.
Forbiden by the convention of genova !
See you soon
Yves
