12. (c) Lessons learned

a. Joint platoon formation proved to be effective under given conditions. No signs of leadership and/or subordination problems, great unit integrity and outstanding performance of NCO’s and EM’s could be seen as a reason for the further implementation of such formations on the fields of battle.

DSCF2928

b. Chain of supply was horrible. THe NCO’s responsible for such mess with the rations should be questioned by higher authorities since the TF was provided with only 2 (two) meals choice instead on 12.

c. NCO’s should take English writing test at 90th RB. d. All infantry troops deploying to the BAO TRAI area should take additional mountain training.

a. Herewith I request Task Force RALEIGH Headquarters to award SP4 van York, Jan with the Bronze Star Medal for his brave and gallant actions during the attack on the 1st Platoon on the August 4, 1968 which led not only to non-casualties engagement, but granted 1st Platoon a possibility for an effective counter-attack leading to elimination of the enemy attacking force.

b. SP4 Sheffield, Jonh recommended for 3 day R&R leave at China Beach
