其實嘛…Jobli一直在吵的是他堅持一定要當
場試射之後才能效力射，問題是實際上是這
樣嗎？
這裡我們在討論的是反登陸條件下的陣地戰
，所以請先不要亂入不相關的情況。什麼打
新莊會偏到板橋去，拜託不要亂入。
那到底能不能？前面有人說了，二戰時的日
軍就做得到啊！靠著陣地把美軍打得措手不
及。你說那是榴砲，迫砲不行？那我們來看
美軍準則好嗎？美軍有說效力射之前一定要
試射嗎？
沒有。事實上，美軍的準則很明確地把不試
射直接效力射當作一種奇襲手段，因為會讓
對方來不及躲避。海陸的準則是這樣寫的（
陸軍的也差不多，我就不重複了）：
“2-128. Firing corrections within the
transfer limits should be maintained
through registration, survey data, and
current MET message. When those data
are unavailable or inadequate, targets
should be attacked with observed fire,
since unobserved fires may be ineffective.
Surveillance should be obtained on all
missions to determine the results of the
FFE. If accurate, firing for effect without
adjustment is highly effective against
troops and mobile equipment because
damage is inflicted before the target can
take evasive action. All destruction
missions and missions fired at moving
targets must be observed, and FFE
should be adjusted on the target.”
簡單地說，美國準則只有說實施效力射應有
前觀觀測確定落點和效果，並且供之後調整
，但並沒有說必須要先試射，反而是說，如
果可以準確地直接進行效力射，對於敵部隊
和機動裝備的打擊效果很高。
然後，準則也很明確的提到一些限制。彈藥
消耗就不用說了，準則說供應量高時才能用
，但這對臺灣不是問題，畢竟是在自己主場
。準則這樣寫：
“2-131. The amount of ammunition available
is an important consideration when attacking
targets. The controlled supply rate (CSR)
should not be exceeded except by the
authority of higher headquarters. When the
CSR is low, units should fire only those
missions that contribute the most to the
supported units' mission. When the CSR is
high, units may fire missions that include
targets that affect planning or future
operations and targets that require massing
fires without adjustment.”
然後，還有一些零星的限制和注意事項就
請自己Google，反正那些對於以陣地戰進
行反登陸的一方而言不是太大的問題。
所以，不是我亂講，是你們因為某些原因
根本不知道可以這樣。
