'fraid not Predatorplus. 621 EOD Sqn part of 11 EOD Regt RLC is also based in London at Northolt ( you could argue that it is Middlesex but it is on the tube and inside the M25 and London District says its London) but you are correct the only EOD unit is 521 EOD Sqn again part of 11 EOD Regt RLC but no sappers in the EOD role.
Ask him how many rockets go on a rocket wrench?
I know of an RE Staffy who passed his JSIEDD and was selected to become an instuctor at the Felix Centre. Prior to undertaking this appointment he spent approx 6 months doing duties at Catterick Tp, 521 Sqn, 11 EOD Regt RLC.
i thought that 11 Rlc (eod) did all the rapid responce / counter terrorist bomb killing??
from what iv been told is that the RE bomb disposal deal with mine feilds, bad guy ammo dumps etc although some RLC may do this work but are more for the IEDD
or as my friend put it '11 do it like a heart transplant, and RE jump up and down on it to see if it will still go off'*
Ask him which Sqn, which troop and which EOD cse he was on and where (if he can't come up with the right numbers... especially if he really said he is based in Wimbush (never been there but Grim[Wim]bish was enough))
