9. REBUSHINGS. Note this block is used for accountability of breech as it is replaced. If the initial breech is in the gun, place a zero in
this block. Upon first breech replacement, the zero is changed to a 1 and so on. When a breech is replaced, a note is placed in column
10i (remarks) to include date breech was changed and total rounds on the weapon at the time of replacement. The remaining life
column, 10h, upper portion, has 25,000 placed in it at the time of breech replacement to reflect remaining life of the new breech.
10. This block is divided into columns a through j:
Date a. Enter current date.
Projectile Type b. Enter the type of round fired.
Zone or Charge c. No entry required.
Rounds Fired d. Enter number of rounds fired.
EFC RDS Fired e. No entry required.
Cumulative RDS Fired f. Add the number of rounds fired (last entry 10d) to the last of this column.
Cumulative EFC RDS g. No entry required.
Remaining Life h. This block is divided into two sections by drawing a horizontal line from side to side in the middle of the block. The
upper portion contains the rounds remaining for the breech and the lower portion contains the rounds for the firing pin. Each time, an
entry is made in 10d, the same entry is subtracted from the last entry for the breech and firing pin in 10h. This subtraction yields the
remaining life in rounds of each of the two parts. When a part is replaced, the remaining life block shows this by adding either 8,000 or
25,000 in the appropriate portion of this block.
Remarks i. This column is used for replacement information as described in paragraphs 8 and 9.
Signature j. The unit commander signs in this column on the first and last entries. The unit commanders signature shows that the
information on the previous form has been checked and found correct. Also, that all current and necessary information has been
transcribed to a new DA Form 2408–4. The person designated by the unit commander signs name and rank on the entries between the
commanders two signatures.
