Note 417 — Chapter VIII · Marking Time (April-June 1953)
Reading edition
The tanks were not kept in exposed firing positions at all times. They were parked in protected, defilade revetments and were periodically driven into the firing slots to zero in on targets of opportunity. One tank might thus use any of several slots, and in cases of major attacks reserve tanks could reinforce. LtCol Robert J. Post ltr to Dir, MCHist, HQMC, dtd 28 May 70, hereafter Post ltr.
