The Chieftain was the first MTB to be mass equipped with a laser range finder. the Barr & Stroud LF2 from ~1970 onwards.
It was installed in the Mk3 - 3 upgrade.
So while the Mk3 didn’t have one initially it was upgraded with one so whether or not it should be included in game is debatable.
Given that the Mk3 gets a 8.7 battle rating and is matched with significantly more modern tanks which all include laser range finders then for the sake of balance the Chieftain Mk3 should be upgraded to its 1970’s MK3 - 3 upgrade.
The MK5 should just 100% have a laser range finder.
Yeah. The biggest Power spikes as the BR increase’s are Laser range finders, APDSFS ammo and gun stabilizers. Chieftain gets 1 out of 3. Most comparable 8.7’s get 2 out of 3 or even 3 out of 3.
It has terrible mobility. And while it does have above average Armor for its BR that kind of means nothing. Having 50mm armor or 200mm armor is basically the same thing when everything is shooting 300mm+ pen APDSFS at you.
If you look at the other 8.7’s.
M60A1 Rise. Stab + APDSFS ammo, No LRF
T-62. Stab + APDSFS ammo, No LRF
Object 122MT. Stab + APDSFS ammo + LFR + Secondary ATGM weapons. (Damn China might be winning the best 8.7 in game with that one)
AMX-30B2. APDSFS ammo + LFR , No Stab
So Chieftain would still be right at home at 8.7 with a LFR + Gun Stab and no APDSFS ammo. That way it would get 2 of 3 of the main power increase’s like most of the other comparable tanks.
I would find it more interesting if the Chieftain Mk5 were given the L15A5, and that the performance difference between the L15A3 and A5 be investigated.
