Okay, since you asked, we'll cover the Vulture Mk. IV Prime
First is Type. Well, that's obvious, it's a BattleMech or BM
Next is Size. At 60 tons, it's a Size 3 Element.
Third is Move. The Prime has no jump jets, so it has a move of 5 * 2 = 10"
Next is Armor. Here's where we get into some interesting stuff with Ferro-Lamellor armor. The Vulture Mk. IV has 201 points of F-L armor. Normally 201 points translates to an Armor value of 7, but Ferro-Lamellor multiplies your armor by 1.2, giving us 241.2 (rounding up to 242) for an Armor value of 8. Not bad.
Fifth, we have Structure. A 60-ton 'mech with a Clan XL Engine has a Structure value of 3. (Side note: The Mad Cat Mk. IV with its XXL engine has a Structure value of 2)
Next is Damage. Firsts we figure out how much heat the Prime builds. With 2 ER SPL, 1 ER PPC, 4 SRM-6, and an LB-5X, the Prime can generate 40 heat at a running alpha. With only 24 dissipation, even the basic -4 bonus will probably not prevent damage loss from heat.
What's more troubling is the fact that with only 7.5 shots for each SRM-6 launcher, the Prime fails to have sufficient ammunition for its missiles, reducing their damage output, but not their heat buildup.
So, Short Range Damage Value. 2*5.25 (ER SPL) + 4*6 (SRM-6s, downgraded for lack of ammo) + 15 (ER PPC) + 2.46 (LB-5X) = 51.96
51.96 * 24 (dissipation) / 36 (40 buildup - 4) = 34.64 for a Short Range Damage Value of 4
Medium Range sees the base damage increase by 0.69 for the LB-5X for a total of 52.65 * 24 / 36 = 35.1 for a Medium Range Damage Value of 4
Since Medium Range also determines the Overheat value, we notice that heat buildup reduced the Prime's damage from 6 (52.65) to 4 (35.1), for an Overheat Value of 2
Finally we have Long Range. Here the Prime gets some luck. Only generating 18 heat from the ER PPC and LB-5X, the Prime suffers no reduction in damage value. So 15 + 3.15 = 18.15 for a Long Range Damage Value of 2.
PV is 2,110 / 100, rounded normally so 21
Lastly, we have special abilities. As a BattleMech, the Prime gets SRCH, SOA, SEAL, and ES. As an OmniMech, we can add OMNI to the list. As a Clan 'Mech with explosive weapons, we can add CASE. Finally, the Prime has enough SRM capability to gain the SRM special for alternate munitions (and be vulnerable to AMS). 24 base damage * 24 / 36 = 16. This rounds normally for an ability of SRM(2/2).
All told, the stat line for this machine is:
