Every one (cadet AND staff) likes to think that they HAVE to have everything… and ahead of time.
In an ideal world and one without budget constraints, that’s great - but let’s be realistic…
For a start, no cadet should ever be told “you can’t do XXX because you haven’t got the right bag (or whatever) - unless, it’s a matter of safety / appropriate for the activity and you don’t check with the activity directing staff.
(For example - you’re mean to be doing your DofE and you rock up with a suitcase…)
I would expect most camps to be capable of being able to contend with any form of luggage, if push came to shove.
I would also expect every Sqn to be able to loan you hold-all, Bergen or other pack of required - or - be able to source it from other Sqn or WHQ.
Working out what you’ll need to take - how long you’re away for - do you need greens, blues, No1s, civvies - what type of weather - bedding… and lastly is accommodation in tents, or buildings…
A bag for a weekend’s Fieldcraft is going to be different to a week of summer camp, with official visits…
Planning staff should be well aware of how much kit cadets (and staff) are going to need to bring, so that they know how much space they’ll need to transport it all…
But probably most important of all…
Can YOU or someone else reasonably pick up and carry your bag without injury…?
There is a high likelihood that you will be expected to carry, wheel or drag your bag from the transport to wherever you’re sleeping…!
