Stubby gun firing stubby shell with more volume for the shell than the casing. Starting from 75mm.Will they ever make a come back for unmanned ground vehicle to occupy land at the lowest cost?>Inb4 mortarLogistically sound choice but muzzle autoloading is more awkward than breachloading and time fused beehive/net shot from arbitrary angle will be integral for swatting nasty flies if drone detection improves.Plus a little more velocity.
>>64991284>MortarsBreech loading mortars exist and you can just mount them on a dual-purpose turret.
>>64991284>75mmWhy would they when proven belt-fed 40mm systems exist?
>>64991785This.
>>64992362Cute.I love box on wheels/track designs.
>>64991284
>>6499232940mm is good for lighter vehicle muting a firing position but it is not going to send the shell through the wall of a wood or brick house.

>>64993768HAHAHAA! Son, you have no idea.
>>64993768if I shoot 20 HEDP into your wood or brick house, it's going to be missing one or more walls

>>64991284I'm surprised they didn't make any appearance in Ukraine from western lend-lease. I know there were never huge amounts of them, but surely there wear a few of the old engineering tanks laying around that they could have sent. Obviously they'd be of no use now, but they would have worked up until about late 2024. The Ukrainians really liked the HESH shells the Brits sent with the challengers and I remember old footage where a Ukrainian tank is just pumping round after round of HE into a russian trench (eventually running out of ammo and then grinding down the trench with it's treads). Surely a low velocity gun would have been better for the job.
>>64995022Buddy road trip movie except they're in the ETO and the car is an M8
>>64995055>Private, you see this Kraut pillbox?>Yes sir!>I don't want to
>>64991284They are cool. The concept peaked with the M551 Sheridan imo. Serval is my favorite, 60mm mortar and 20mm autocannon combo
Also the concept is still in use with the BMP/BMD and the chinese knockoffs. 100mm low velocity gun which can also fire missiles.
>>64995055and the modern-ish version with a 165mm
>>64993768Maybe not, but it will be sending fragments of wall and jets of copper into whatever is standing behind the wall
>>64991284I hope stubby guns make a comeback, I don’t care about effectiveness they’re peak design
How would it fare in Ukraine?
>>65000931Someone explain to me the compass markings on Marine? Tanks. I can't see how it can be useful.
>>65001020Gives external spotters a reference to guide the gunner with
>>65001000It is getting there. Takes time to evolve crabs.
>>64992329Explosive mass increases exponentially with diameter.Of equal length, a 40mm shell has 1/4 the explosive mass of an 80mm shell.Also a larger diameter shell has much more potential against armoured vehicles for rounds like HESH or HEAT.
>>65002147Faggot, I could put three HE 40's on the wall of any structure that wasn't rebarred concrete and blow a hole in it the size of your mother's cunt back in the day. And fuck right off thinking mid-bore low-velocity shit works like HEAT versus real armor. You're talking directly out of your ass so hard you've got projectile diarrhea of the mouth.
>>65001020This tank (Centaur Mk.IV) was used in Normandy, and the markings were drawn on to help the tank be used as indirect fire.
>>64991284Centurion AVRE my beloved.
>>65001020>>65004366IIRC they were used for indirect fire while on the landing craft, basically acting like ersatz naval guns. These were also some of the few Centaur tanks to see any kind of combat.
>>65004366>help the tank be used as indirect fireYes, but HOW? It would be useful to have the azimuth marks painted on the inside of the landing craft the way Observer Corps pits had, but how would you use them for guiding a tank onto a target?
>>65005523*them > these
>>65005523The bearings are relative to the current facing of the turret from the perspective of the outside observer looking over the tank at the target. If you were standing directly in front of (and above) the gun looking at a target behind the tank, you would see it aligned with the 180 marking and be able to tell the gunner that the target is at his 180
M113 FSV, low pressure 76mm gun from a Scorpion.
Always thought they should have made the 152mm on the Sheridan and M60A2 into a large-bore infantry support platform.
The cutest!https://en.wikipedia.org/wiki/7.5_cm_leichtes_Infanteriegesch%C3%BCtz_18
>>65009932>H35 Technically an H39, has the longbarreled 37.
>>65013800we can go smaller!
>>65008553Makes sense. Thanks.
>>64991284Russians had this with bmp-3 but that vehicle was over designed. AAV had it with the 40mm but they got retired. It seems most militaries are obsessed with high velocity long range combat now so the infantry must suffer as always.
>>64991284Always liked the NONA. Good modern system, 1980s Soviet system. Good low intensity size. Hybrid ammunition and also a mortar. Pic of the ammunition.
>>65021826France did something similar, though with smaller 60mm and 81mm mortars, which could fire conventional HE or HEAT for use against tanks. They even developed an APDSFS projectile for the 60mm one, though it arguably performed worse than the HEAT ammo.
