Which unit?

Hi, i am a 21yr ld bloke and looking to join the army soon.

I want to go infantry but cannot decide between Paras or Mercians.

I like the idea of paras as they are a top unit but also would like to join my local county regiment, where several of my mates already are.

i realise that these days with afghan all units go and fight the same enemy and all that so was wondering if any one with experience could offer advice.

i have seen that any thread mentionin paras will get abuse so i am sorry in advance.
