I'll try and decipher these hieroglyphics.
Frogfoot is a MEC bomber plane I believe, though not sure.
Dolphin dive is better explained by someone else as I don't do any of that gay shit and hence don't know how to explain it.
Stinger is an Anti-Air fixed emplacement.
AAA I presume you mean AA, anti-aircraft
BR is Best Round, your best score in a round
Squad hopping is no longer possible, but it in pre patch 1.3 days it was when you would die, join another squad near a flag and respawn on your new squad leader OR in clan matches it was when 5 guys spawned on their squad leader at an enemy flag, then left the squad and formed their own squad and others spawned on them, etc.
CTD is crash to desktop, the infamous problem that plagued patch 1.3. Don't know if others still have it now with 1.4 but for me it never happens anymore.
Cartillery is when you use vehicle drop as a weapon, for instance to drop on a piece of armor at one of your flags or on an artillery mast to destroy it. It is not such a big problem since 1.4
IO means Infantry Only
Hope it helps try speaking english next time.
