What advice can you give for planning a Mortar Gunnery?

2016-11-29T14:56:38-05:00

I am planning a Mortar Gunnery but I am not finding a lot out there. I see FM 3-22.90 - Mortars, but it really don't go into Gunnery and the requirements of going into a live fire. I believe there are some new publications coming out but is there anything that hits on the Tables and Gates in one publication. I am focusing on 120mm in a M113. Does anyone out there have their plan or can share their insight.

It's been a long time since I last sang "That's the life of a mortarman", CPT Private RallyPoint Member, but the rule of thumb back then was that live fires were executed as either an ARTEP or a practice ARTEP. Generally, beyond putting in some time testing mortar gunnery skills (using the SQT standards in the 11C10 Soldier's Manual) and making sure that our tracks were operational (when I was in Cav and Mech Infantry units), we didn't do any other extensive prep.
Actually, there was one significant exception to that: when I was commanding a California National Guard mortar platoon, I force-fed the NCOs a lot of FDC training, because nobody in the platoon knew how to plot fire missions (they had "borrowed" FDC personnel from sister battalions for at least a couple of years prior to my arrival). So my bull-headed insistence that they would, by God, pass their ARTEP using only organic personnel meant that I had to train them for that aspect (I also served as the safety computer during the live fire).

I wish I could help you CPT Private RallyPoint Member, but my indirect fire infantryman days ended on 16JUN73 as an 11C4S! Just wanted to say hello and wish you good luck in your quest!

Not sure of the changes in FM's, but FM-23-91 Mortar Gunnery covered the execution of live fires and the gunners exam. Also, FM 7-90 Tactical Employment of Mortars is good reference for planning an FTX, but not much in gunnery itself.

Insure your weapons card (2408-4) for each tube is up to date and tube borescope and pullover has been preformed. This is done by Field Maintenance IAW TM 9-1000-202-35 Evaluation of Cannon Tubes and local policys. Tube is not to be fired if 2408-4 is not up to date. Have seen many sad faces when thwy were not allowed to fire because of this.

When a similar problem arose at Ft Bragg (many years ago in the days of manual gunnery and "charts and darts" the artillery FDC 13Es were very helpful.

My last time firing a mortar was on the 4 Deuce and the only thing I would be able to add is get the entire platoon up to speed on all their basic skills, especially the 2 gunner they have to really be up to speed in getting your unit laid in. Second let them acclimate them selves on the old school way of FDC and being able to hit and estimate ranges on visible targets. First time I did an FTC on this I was the 2 Gunner and I was hitting visible targets metal on metal. Hell to make it even weirder I was the Driver of the M1107 I think that is the old nomenclature of the mortar carrier. Since they are Vehicle Mounted that is a good place to start is doing it the way they would be doing it in Real Life with the current Equipment you have. Have them completing this without notes.

"Hey Little Dittle, Far pole in the middle." remember that when your registering your motors and putting in your poles.

Go old school for gunnery, find a plt sgt frrom the 80's. That was fun and lots of competition

Mortar gunnery is now know as Mortar certification. It falls under DivArty and you can find the DivArty pub on the 7th Id page for JBLM. Also some other helpful pubs are Mortar Platoon Collective task Pub TC 3-21.90 aug 2013
ARTEP 7-90-MTP mission training plan for the infantry Mortar plt. Section and squad. Apr. 2005
And Tactical employment of mortars ATTP 3-21.90 (FM 7-90)/ MCWP 3-15.2 Apr. 2011
There is no longer an updated gunnery/ Mortep manual sir. My best advice would be to link in with the senior Mortar PSG's and your brigade fecc specifically the target acquisitions officer for guidance on your brigade's standard for Mortar Certification.

Yes..There is one publication. I wrote it while I was at the MCOE on Benning as a doctrine writer for 11c's. Reach out to the Gunnery Doctrine Branch at MCOE..ask for a Mr. Steve Krivitsky or Keegan Becker...they whole get you what you need. In the pub..all tables and gates are outlined for you

First if your looking at heavy mech inf. With the 120mm, you will be in a 1064, not a 113. Best advise foe you is get away from the books find a unit that's doing a live fire training exercise and request to tag along as an observer.

Hey LT. You have a lot of feedback here. I retired in 2007 after 20 years as 11C40. Ran 60mm and TN 81mm. Best advice I can offer is to use your experienced senior NCO's.
I will be curious to see how it all panned out for you when it's done.

Every Mortar gunnery I've done has been different. Everything depends on your unit and bases SOPs as far as what they are looking for. Get with the other PSGs across base they should be able to help you figure out the SOP for where you are. Also what SFC Fullerton said is spot on.

Get a hold of the Department of Doctrine and Training at the Maneuver Center of Excellence on Benning. Bldg. 4. Ask for Mr. Curtis Archuletta, or Mr. Jergan Becker. There are new tables that I wrote 2 years ago, that haven't been published, but its already been vetted by 3ID and is supposed to be in final editing. Those two gentleman should be able to help you. Tell the SSG Eaken told you to contact them.

Your FDC will give you all the numbers, Deflection and Elevation, dial them in, if off, your FO will give the corrections to the FDC.
A good FDC can get your round in a can, then give you 9 cents change back.

If possible, have all of your soldiers take the Gunner's Primary Exam before heading up to the range. That will give your Plt Sgt time to focus on those that are having trouble
