It's not CSAD anymore, supposedly para/cdo EOD troops for short notice deployments with EOD/ECM/search bods all together ready to go. Not sure how its going to work with licensing and the like though, as far as I can tell the operators won't be doing anything when not deployed apart from usual regimental admin. The leftover troops from 921 Sqn disbanding are being given to 521, 621 and 721 as CSAD troops the last I heard.
It will be the place that is trawled for all overseas ops in the future, with 11 Regt only supplying support for UK MACP.
If supported properly it will be the unit everyone will want to be posted to but not the location.
The plan is for the unit to develop its own licencing criteria. A lot of work still needs to be done on this.
As of May CSAD will be covered by 521, 621 & 721 in turn a month at a time.
