This is not fiction. It is tanks produce coverage and a break through fortified, not as rare a tank duel. In the front projection tank almost frightening contact with ATGMs.?he tank should only be fought with tanks or other large gun emplacements, and support combat vehicle or heavy IFV with tank hazardous purposes.
Of course, I agree tank is irreplaceable as a break through vehicle, however tank on tank scenario is more than rare. Originally, I argued your point that 30mm cannon as an addition will not burden the crew, it will just give them more tools since in almost every scenario I know tanks are pushed into urban combat. To put it simple, I more or less agree on point save for one: adding a high-elevation heavy anti infantry weapon will burden the crew.
Here is a piece of discussion, I can't translate it right now, so can only give a link in Russian:
Gur Khan attacks!: ?????? ?????????
The main problem is "30mm cannons are insufficient".
Read it. Good article but IMHO misses on a few things.
Yes, there is a lot of talk about 57mm cannon and yes it is surely much better at anti infantry role. It does combine best of 2 worlds, playing medium between 30mm (rapid fire) and 100mm(destructive, variety of charges), I realize that but there is little talk of drawbacks. For example, ammo supply, turret rotation speed and so on. Let me elaborate what argue in short:
30mm ammo is rather common thing in RA, something that people often oversee. Its used on AA platforms (Tunguska, Pantsir), both fighters and strike aircraft (gsh 30mm), helicopters, BMPs, BMD, BTR... So yea, quite common is understatement so supplying ammo is no logistical nightmare. on 57mm side, not so much.
Turret on BMPT, rotates quite fast, has excellent elevation/depression and has 2 rapid fire 30mm autocannons. Bear in mind were talking about
anti personel weapons here, and its use is to protect MBT (heavy hitter) from infantry (not from other armor). 2a42 is a rapid fire weapon capable delivering similar rate of fire (up to 800 IIRC) as
assault rifle while delivering whole ~400g of fragmenting projectile on target. That is, how to put it... More than sufficient for anti infantry use.
I stand behind my statement that dual 2a42 turret on BMPT is a very
very nasty piece of machine and that its quite adequate for its designated targets. Mind you, not original BMPT with grenade lauchers but bmpt-72.
Now t-14 changes the game a bit but as usual having its own 30mm, well have to wait and see.
