The company spent time on Salisbury Plain in Wiltshire, and then travelled to Inveraray in Scotland where they underwent specialised training on Loch Fyne, practising night embarkations on landing craft to prepare the company for evacuation by sea after raiding the radar installation.
After this, the unit returned to Wiltshire and began carrying out practice parachute drops with the aircraft and aircrews of 51 Squadron.

Despite the aircrews having no previous experience in dropping parachutists, these exercises proved to be successful.
The company's working-up was aided by the creation of a scale-model of the radar installation and the surrounding buildings being built by the Photographic Interpretation Unit.
During this period, Major Frost was introduced to Commander F. N. Cook of the Royal Australian Navy who would be commanding the naval force intended to evacuate the company at the completion of the raid, as well as to the detachment of thirty-two officers and men from No.
12 Commando who would arrive in the landing craft and cover the company as it withdrew from the beach.

Frost also met RAF Flight Sergeant C.W.H. Cox, who had volunteered to accompany C Company for the operation; as an expert radio mechanic, it would be his job to locate the Würzburg radar set, photograph it, and dismantle part of it for transportation back to Britain.
Derek Garrard of Jones' team asked Jones to obtain an Army uniform and identification number for Cox, as he would be the object of special attention from the Germans if he was captured in Air Force uniform, but the War Office were obdurate.

Accompanying the strike force was a 10 man section of Royal Engineers of the 1st Air Troop led by Lt.
Dennis Vernon.
Six of the sappers would dismantle the radar device whilst four sappers would plant anti-tank mines to protect the force from counter attack.

Information about the Bruneval radar installation was also gathered during this period, often with the help of the French Resistance, without whom detailed knowledge of the disposition of the German forces guarding the installation would have been impossible.
This information was gathered by Gilbert Renault, known to the British by the code-name 'Remy' and several members of his resistance cell.

The installation was composed of two distinct areas; a villa approximately 100 yards (91 m) from the edge of a cliff which contained the radar station itself, and an enclosure containing a number of smaller buildings which contained a small garrison.
The Würzburg antenna was erected between the villa and the cliff.
The radar station was permanently manned by Luftwaffe radar technicians and was surrounded by guard posts and approximately 30 guards; the buildings in the small enclosure housed about 100 German troops, including another detachment of technicians.
A platoon of German infantry was stationed to the south in Bruneval, and was responsible for manning the defences guarding the evacuation beach; these included a strongpoint near the beach as well as pillboxes and machine gun nests on the top of the cliff overlooking the beach.
The beach was not land mined and had only sporadic barbed-wire defences, but it was patrolled regularly; a mobile reserve of infantry was believed to be available at one hour's notice and stationed some distance inland.

Based on this information, Frost decided to divide the company into five groups of forty men for the raid, each named after a famous Royal Navy admiral: 'Nelson', 'Jellicoe', 'Hardy', 'Drake' and 'Rodney'. '
Nelson' would clear and secure German positions defending the evacuation beach, whilst 'Jellicoe', 'Hardy' and 'Drake' would capture the radar site, villa and the enclosure. '
Rodney' was the reserve formation, placed between the radar site and the main likely enemy approach to block any counterattack.

It was considered that the combination of a full moon for visibility, and a rising tide to allow the landing craft to manoeuvre in shallow water, was vital for the success of the raid, which narrowed the possible dates to a four-day period between 24–27 Febru
