when assembling a phib assault, create a separate phibTF consisting of 1xAGC to load the phib Force LCU, then merge it to your main phibTF as Schanilec suggests. the entire LCU should load aboard the AGC, regardless of cargo-size constraints (iirc). it serves to accelerate unloading at the assault target, & will stay aboard until everything else is unloaded.
AGC in the AmphTF gives an unload benefit, AGC w/ embarked ForceHQ gives a better benefit, AGC + ForceHQ w/ high-$ leader gives the best benefit.
so as your assault proceeds, transfer the emptied transports & ammo-depleted escorts to a new TF, transfer your 2nd wave of shipping & escorts into the AGC's TF.
i used to think that an embarked ForceHQ's leader gave a land-combat bonus to dis-embarked assaulting LCUs, but i got shot down on that awhile back - now i believe that a ForceHQ improves unloading only, & only if it's riding in an AGC. if it's loaded on another ship type, it'll unload normally but will NOT function as a std CorpsHQ for land-combat.
wwengr's report on 'How to choose leaders' lists 'land skill' as the only valid skill for a ForceHQ, to improve its unloading benefit. RKTurner is the best commander available for a ForceHQ, imo you should leave him there.
