Rising from the ranks? (12)

I haven't cracked this one yet — but the brilliant team at Fifteensquared have:

Not sure what ‘from the ranks’ means, unless insurrection specifically means a military uprising of some sort. 2. APERITIFS . PARTIE(IF)S*. 3. ELDER . EL + RED<. 4. INELASTIC . ACTILINES*. 5. DUCK . ‘Get down!’.  Also took me a while to realise that you get down (feathers) from a duck. 6. CHA-CHA-CHA . Cha = tea. 7. TITAN . TIT + A + N(orth). 9. COPPERSMITHS . COPPER + SMITHS.  Smiths are ‘forgers’ because they use a forge. 13. MISERABLE . MISER + ABLE. 14. CAMEMBERT . CA(MEMBER)T. 16. ATTRIBUTE . double def. 20. DROVE . (lan)D ROVE(r). 22. OFFAL . OF + FAL. 23. EDGE . double def (sort of – both defs are the same sense really).
