CRSC supplemental paperwork

[169749942]

Good morning. Is there a suggested form/letter that can be completed by a military command to help justify a CRSC claim?

The forum's CRSC resources state:

A signed claim form (DD 2860), DD-214, DD-215 and other typical official documents include, but are not limited to VA narrative summary letters and VA code sheets, service medical record extracts, military personnel file extracts, military personnel data system printouts, prior military disability board decisions, line of duty determinations, safety mishap (accident) reports, next of kin notification (Western Union Telegrams), casualty reports, morning reports, duty status reports, order/travel voucher, official documents not in the military personnel record, etc.

My injury was during required pre-combat deployment training and I believe the injury would fall under the "Simulating War" section. The command (not my current) is willing to write a letter stating that:
- Would describe the events (Similar to "Sprained ankle on tactical road march" situation)
- That the event was a required part of pre-deployment training
- That the injuries occurred during that event

Is there any other supporting information that I'm missing that would be beneficial? Thanks in advance.
