I have a few reliable sources on the subject, one a personal one and the chap who taught me, although I went the G2 route in the end and SABOT from the Guild. Both these chaps have a massive amount of knowledge working with and instructing armour. A clip stolen from the guild:
The time given above to spot / aquire targets at 20 seconds??? Not a chance, any turret crew that took longer than a few seconds would be sacked after failing assessment Exercise Juliet – single crew evaluation through to Exercise Oscar – troop Battle Run.
There is no such thing as applying suppressive fire from MBT`s – no way.
Move after firing 4 rounds – again complete nonsense. No drills were ever laid down for this as an SOP except kill the target , 80% of the time first round kill – then jockey by reversing out of the field of view of the enemy and reappear and engage again. No technique would last more than three rounds KE but yes, CE engagements could be four or five rounds (usually three on average) but CE engagements mostly against targets that could not kill you at the same range band.
Some AFV`s not firing – not a chance. No way. Our problem in Gulf 1 was over kill. Because the signature from a hit using APFSDS was minimal often each Callsign fired into the same target more than once til it was def dead. Tank crews do not get to choose when to engage either , i.e. "think I will hold back here" as Troop fire control is standard practice in all NATO armies. The centre callsign calls the `Bill` total targets arrayed and each C/S claims or is designated.
On the air sounds like this……
"Hello all stations this is One Zero – watch your front!"
Hello One Zero this is One One ( troop Sgt) One right – mine out!" He then engages.
Two more targets appear …
"One Two (troop Cpl ) this is One Zero (Troop Leader), two left , split!"
Another target appears ….
"One Zero One One – single right – mine out" and engages.
Troop Leader spots another and is engaging a previously spotted target so has to designate to the callsign least busy….. that`s One Two….
" Mover left One Two engage!"
Troop leader during lull (if there is one!) One One and One Two One Zero FIVE – destroyed Over?"
" Roger Roger " from both flanking callsigns who then MRS and prepare to move ( Jockey) During jockeying may need to restow ammo to ready round bins but only two max will move and one remains overwatch then they switch.
As for the Sovs, firing at the short halt was the norm, using "volley" fire to bring in the maximum of shots on a target.
Tally Ho!
