Career- Army First or FireService?

[Zero]

Ok i know iv been asking a few questions on joining the army etc, which i still plan to do, however im wondering... Would i be better to join the FireService first, for mayb 2/3 years and they join the army? Because i plan to leave after GCSE's but when my friends are at uni etc and going out i want to be able to go out an do things with them, which i would be able to do if i was in the fireservice however if i was in the army i would not? However joinin the fireservice first would mean leaving, joining the army, and then applyin again mayb 5 years later? or would it be better to join the army at 17, serve for 5-10years and then apply to become a firefighter? May be a little hard to understand but basically... Army = 17-22 then fireservie or.. FireFighter = 17 - 20/22 then do 5 years army? and apply to fireservive again? sorry about the awkwardness haha
