Narc isn't great in lance-scale combat, and only really comes into its own at the company scale or larger. Most people don't play company scale,
So true here.
Using tanks as the example.
A mixed Platoon of Zephyr-Regular/Royal or Drillsons + Scimitar-3050 depending on the era teamed up with a Platoon of LRM Carriers & 3rd Platoon of Manticores makes for a nasty support group.
Using Mechs..... I love the 3039 Jenner-Grace as a NARC Spotter, but a Hitman/Owens also works. (Kurita has the best spotters for NARC IMHO)
But take 2-3 of those in a Light lance escorted by Pixie(s) &/or a Spider/Raptor.
Then for your LRM big boys you use Archers, Longbows, Crusaders, etc etc.
Finally a midsized lance centered around Griffins, Whitworths, Centurions & Wolverines for a solid mix of speed/range/firepower.
Only a few of the chassis even need to be Upgraded tech, most can still be L1 models. But you'll rain down LRMs all day with increased accuracy.
It doesn't work quite as well when trying to do that with only a single lance.
Maybe the above Jenner/Owens with a 3050 Treb for backup Narc, then support them with 3025 Catapult & Longbow. Should make for solid mix but it just doesn't have the same feel w/o being a full company.
