One of my fav units.. equipped with the Monomolecular Knife (0.3 kg) and Combat Armour (7.0 kg). This requires a Strength of 37 or higher. In order to stay within the light class every strength beyond 37 is equal to 0.2 kg.
So at Str38 and Str39, I can equip a flashbang (0.2 kg) in the off-hand and respectively, one in the belt. The Monomolecular Knife is an incredibly effective weapon, which you get reasonably early and with high damage values that will continue to be effective for the entirety of the early game, and into the mid game.
As a light, the min TU is 42. Giving you a max range of 21, leaving you:
For 2 Stab: 34TU remaining, Ensuring you a 100% Killing Range of 17 -OH: 14 OR: 13
For 3 Stab: 30TU remaining, Ensuring you a 100% Killing Range of 15 -OH: 12 OR: 11
For 4 Stab: 26TU remaining, Ensuring you a 100% Killing Range of 13 -OH: 10 OR: 9
Smaller Numbers are KR's including use -OH: Off-hand flashbang OR: Off-hand Reserve flashbang ( from belt&holster)
* One Stab takes 4 TU
My experiences with this are that its difficult to implement this unit into the group, as single scouts they are effective at spotting the enemy contacts, but with a tendacy to seperate/isolate themselves.
I've had better results using 2, but due to the increased mobility still get caught in situations with out backup. So I'm trying to use them together as a sort of self-contained scouting unit.
My best results were using this unit exclusively, took three on a base defense vs 7 aliens: light armoured taman/shevaar with plasma blasters/rifle and a few hovernets, one of which scored the only hit against me. I won in six turns but I'm seriously hoping to find a better way to usefully intregrate within a larger group.
