I want to be in logistics and support and get my hgv but I know nothing about vehicles will they teach me?

Great question, The British Army will provide you with all the training you need to do your job, including driving theory and tests. Once complete, these civilian qualifications will be added to your driving licence. You'll then learn to drive military vehicles: developing cross-country and night driving, amongst other skills at the Defence School for Transport in Leconfield. There's no additional cost to you, in fact you'll be paid whilst you're learning to drive. Like Graeme said, there's no need to worry about having any prior knowledge, the course is designed to take you from "Zero" to "Hero". If logistics and support is something you're interested in, have a look at the Royal Logistic Corps. The RLC is the British Army's logistic power and you can get your Cat B, C+E in every entry-level trade. Search "Royal Logistic Corps" in the Army jobs website here to learn more about what trades are available: https://jobs.army.mod.uk/regular-army/find-a-role/ There's also some good content on the main Army website: https://www.army.mod.uk/who-we-are/corps-regiments-and-units/royal-logistic-corps/rlc-careers/
