I created some mercenary upkeep rules for the Battletech campaign we are playing. The previous C-bill based version was a bit of a headache, but the war point version from Catalyst's "Chaos Campaign" tracks is a bit easier and more flexible. The minutiae of Battletech campaign finances might not be of interest to you unless you are running a campaign yourself, but I figured I'd throw it out there in case someone else wants to mine it for ideas.
I totaled up the war points my son secured after his campaign on Vantaa, and updated his "Current Assets" to reflect mech losses to enemy fire and salvaged mechs that haven't been repaired yet.
Using a random mech availability table I rolled up some possible additions he could add to his force: 8 light mechs, 7 mediums, 3 heavy and 2 assaults (that seemed about right to me). Mechs could be junkers and salvage, or could be in fighting shape with its own mechwarrior pilot. Each mech had a chance of being crippled (25%), damaged (25%) or ready (50%). If a mech was ready I rolled up a pilot (Green, Regular, Veteran or Elite) and picked a call sign for them. The cost for each was taken from the Chaos Campaign chapter in Strategic Operations.
My son picked up some of the crippled mechs to give to his dispossessed mechwarriors and rushed repairs on them resulting in some missing armor (the P-Hawk only has like 2 armor left on one arm - permanently!) and a machine gun on a Locust that can jam. It needs some tweaking, but overall it worked pretty well.
Next time - Assault on an Ice Planet!
