mounted gunners


right, ive put my first job choice as junior entry RHA. i want to go 7RHA in the future, how would i go about doing this, recruiters not much help sorry if it is a stupid question.
I think its the "Horse" bit that has confused the poor dear.

Peraonally I fail to see what throwing horses at the enemy is supposed to do.
The only mounted Gunner Regiment we have is our Ceremonial Troop 'The Kings Troop Royal Horse Artillery' based in St Johns Wood, London. 7 Parachute Regiment Royal Horse Artillery (RHA) are not mounted, as the name may suggest, neither are 1st or 3rd Regiments RHA. If you want more information on being a Mounted Gunner then speak to the Recruiting Sergeant at the Troop, who will be more than happy to help out.
