I looked through 2,507 1/35 figures and here is what I found that you might be able to paint or reshape to make the figures you need. Though a 100 figures could be pretty expensive!
Warriors makes a tank crew #35500 that could be used maybe as warlord figure. Warriors #35505 is a militia man figure. Warriors #35423 and #35424 and #35426 are sets of two Mujihadeens, ADZ #35211 is an Afghan rebel. CMK #35073 are two Afghan rebels. ICM #35221 is a Mujihadeen 4 figure set. Verlinden #1738 is a Bedouin with camel. Verlinden #1826 is a Taliban set. #1827 is two dead Taliban. Verlinden #2049 is two Arabs. DML #3022 is a Somolia US delta force set.
